A) Carnivore__________________________________________________________ B) Primary Producer____________________________________________________ C) Herbivore___________________________________________________________ Place the letter of the term above in its correct spot in the pyramid below: D) What % of energy is passed up through the ecosystem energy pyramid? ________ 2) Fill in the blank with the proper word from the list below. Mutualism Commensalism Parasitism Predator Prey Competition A) You help someone study for a test. They let you play their X-Box. This is an example of ________. B) An example of ____________ is when a bird finds safety from a cheetah in a tree. (the tree and the bird) C) A frog is the ____________ and the fly is the ____________. D) Tapeworms in your stomach are an example of _______________ because they steal nutrients from your body. E) Fish that swim behind a shark and eat its leftovers is an example of _________________. F) __________________ occurs when two species are trying to use the same resource such as fish. 3) For the organism below, list four structures and their functions. Be sure to describe how the function helps them survive in the wild! 4) Explain why deer and lion have a PREDATION relationship. 5) Explain why deer and lion have a MUTUALISTIC relationship. 6) Create a food web with at least 4 animals and 2 plants. On the arrows between the organisms, be sure to explain the relationship between the two. For example: Cow eats grass. ------------------------------------------------------------------------------------------------------------------------------7) From the list below, match the correct vocabulary word for the definition. Niche Adaptation Structure Function Evolution/Evolve Biome Species Habitat Competition Biodiversity A) _____________ Two similar organisms that can mate and create a baby that can also have a baby. B) _____________ Where an organism such as a fox lives is its (blank). C) _____________ The natural process describing how a species changes over time. D) _____________ A part of an organism or a behavior of an organism that helps it survive. E) _____________ Part of an organism, such as its horns, its leaves, or its stripes. F) _____________ The “job” an organism has in its ecosystem. G)_____________ A geographic area with specific characteristics, like a desert, ocean, or prairie. H)_____________ When organisms both need the same limited resource this exists between them. I) _____________ A change that happens to an organism that helps it survive better. J) _____________ The name for the great many different plants and animals that walk the planet. 8) Explain how humans are interdependent as taught by Dragonfly Pond. 9) If all of the biomes in the world were the same, hypothesize what would happen to the amount of biodiversity in the world? EXPLAIN. 10) Is a horse best suited for a grass land or a desert? Explain your answer in terms of adaptations (structures) and functions. 11) Explain why we should do our best to prevent ANY species from going extinct? Be sure to use the phrase “Life Webs” in your answer. 12) _____ Many trees that lose their leaves. A) Savanna B) Taiga C) Desert D) Rainforest E) Deciduous Forest C) Desert D) Rainforest E) Deciduous Forest 13) ______Lots of fir trees. A) Savanna B) Taiga 14) ______Not a lot of moisture but abundant animal life. A) Savanna B) Taiga C) Desert D) Rainforest E) Deciduous Forest D) Tundra E) Grasslands 15) ______Cool temperatures and little moisture. A) Savanna B) Taiga C) Desert 16) ______ Warm temperatures and moisture. A) Rain Forest B) Deciduous Forest C) Grasslands D) Desert E) Taiga ------------------------------------------------------------------------------------------------------------------17) List two reasons why plants need animals. A B 18) List two reasons why animals need plants. A B -------------------------------------------------------------------------------------------------------------------19) Explain about evolution by natural selection using the following terms: population, environment, competition, fittest, adaptation, and extinction. 1) Define the words. A) Carnivore_____An organism that obtains energy from eating other animals_ B) Primary Producer_Organisms that can use photosynthesis to obtain energy – like plants_____ C) Herbivore___________An organism that obtains its energy from eating plants. Place the letter of the term above in its correct spot in the pyramid below: D) What % of energy is passed up through the ecosystem energy pyramid? a A __10%___ B B C 2) Fill in the blank with the proper word from the list below. Mutualism Commensalism Parasitism Predator Prey Competition A) You help someone study for a test. They let you play their X-Box. This is an example of MUT B) An example of _____COM____ is when a bird finds safety from a cheetah in a tree. (the tree and the bird) C) A frog is the ______PRED___ and the fly is the ____PREY____. D) Tapeworms in your stomach are an example of _____PARA_____ because they steal nutrients from your body. E) Fish that swim behind a shark and eat its leftovers is an example of _______COM______. F) _______COMP______ occurs when two species are trying to use the same resource such as fish. 3) For the organism below, list four structures and their functions. Be sure to describe how the function helps them survive in the wild! Striped body / to hide from predators in tall grass; long legs – to run fast from predators, etc. 4) Explain why deer and lion have a PREDATION relationship. Because the lion eats the deer for energy. 5) Explain why deer and lion have a MUTUALISTIC relationship. Because the lion help keep the deer population down and the deer provide them with food. 6) Create a food web with at least 4 animals and 2 plants. On the arrows between the organisms, be sure to explain the relationship between the two. For example: Cow eats grass. ------------------------------------------------------------------------------------------------------------------------------7) From the list below, match the correct vocabulary word for the definition. Niche Adaptation Structure Function Evolution/Evolve Biome Species Habitat Competition Biodiversity A) __Species_____ Two similar organisms that can mate and create a baby that can also have a baby. B) __Habitat_____ Where an organism such as a fox lives is its (blank). C) Evolution____ The natural process describing how a species changes over time. D) Adaptation___ A part of an organism or a behavior of an organism that helps it survive. E) _Structure____ Part of an organism, such as its horns, its leaves, or its stripes. F) ___Niche____ The “job” an organism has in its ecosystem. G)____Biome____ A geographic area with specific characteristics, like a desert, ocean, or prairie. H)___Competition____ When organisms both need the same limited resource this exists between them. I) __Adaptation__ A change that happens to an organism that helps it survive better. J) _Biodiversity__ The name for the great many different plants and animals that walk the planet. 8) Explain how humans are interdependent as taught by Dragonfly Pond. We need to rely on each other. If one group pollutes the water, all of the groups down river from that spot are also polluted. We are connected with each other. 9) If all of the biomes in the world were the same, hypothesize what would happen to the amount of biodiversity in the world? EXPLAIN. Lots of possible answers 10) Is a horse best suited for a grass land or a desert? Explain your answer in terms of adaptations (structures) and functions. Describe some of the structures on the animal that help it live in the hot, arid desert. 11) Explain why we should do our best to prevent ANY species from going extinct? Be sure to use the phrase “Life Webs” in your answer. We are all connected in some way. If you let one species go extinct, it affects all of the species that have a relationship with it, and all of those species, and at some level it will affect humans and all creatures on the planet. We harm animals at our own peril. 12) ___E__ Many trees that lose their leaves. A) Savanna B) Taiga C) Desert D) Rainforest E) Deciduous Forest C) Desert D) Rainforest E) Deciduous Forest 13) ___B___Lots of fir trees. A) Savanna B) Taiga 14) __A___Not a lot of moisture but abundant animal life. A) Savanna B) Taiga C) Desert D) Rainforest E) Deciduous Forest D) Tundra E) Grasslands 15) __D___Cool temperatures and little moisture. A) Savanna B) Taiga C) Desert 16) ____A__ Warm temperatures and moisture. A) Rain Forest B) Deciduous Forest C) Grasslands D) Desert E) Taiga ------------------------------------------------------------------------------------------------------------------17) List two reasons why plants need animals. A They provide carbon dioxide B They spread their seeds 18) List two reasons why animals need plants. A They provide oxygen B They can photosynthesize, or give us energy from the sun -------------------------------------------------------------------------------------------------------------------19) Explain about evolution by natural selection using the following terms: population, environment, competition, fittest, adaptation, and extinction.
