Chapter 2.1 - Ecosystems Topic: What are the levels of the environment? Vocabulary – Use Window Notes: Define and provide an example. Species Population Habitat Niche Community Procedure: (complete individually) • Read section 2.1 using window notes • Answer questions 1-6 from page 51 in your science notebook • Create Levels of the Environment Poster • • Use page 49 as a guide Explain each level of the environment with a real-world example Food Chains Extension Activity Organism Population Definition Example sentence Sketch the example Definition Example sentence Sketch the example Biome Community Definition Example sentence Sketch the example Definition Example 3 facts Ecosystem Definition Example sentence Sketch the example Chapter 2.2 – Interactions Topic: How do species interact? Vocabulary – Use Window Notes: Define and provide an example. Predator Prey Competition Cooperation Symbiosis Mutualism Commensalism Parasitism Vocabulary Practice Symbiosis Quiz Procedure: (complete individually) • Read section 2.2 using window notes • Answer questions 1-6 from page 61 in your science notebook • Create Levels of the Environment Poster (page 49) • • Explain each level of the environment with a real-world example Create Interactions Poster (pages 58-61) • • Fold a paper into six equal sections Illustrate and explain: • • All three types of symbiosis, cooperation, competition, and predation Food Chains Extension Activity Predation Competition Cooperation Definition Example sentence Sketch the example Definition Example sentence Sketch the example Definition Example sentence Sketch the example Mutualism Commensalism Parasitism Definition Example sentence Sketch the example Definition Example sentence Sketch the example Definition Example sentence Sketch the example Interactions Quiz • Number 1-10 on a blank notebook page. • Write down the following vocabulary choices: • • • • Predation Mutualism Commensalism Parasitism • For each question decide what type of interaction best fits. 1) Lion and Zebra • The lion hunts and kills the zebra for its food. Predation 2) Wrasse Fish and Black sea bass • Wrasse fish feed on the parasites found on the black sea bass's body. Mutualism 3) Ostrich and Gazelle • Ostriches and gazelles feed next to each other. They both watch for predators and alert each other to danger. Because the visual abilities of the two species are different, they each can identify threats that the other animal would not see as readily. Mutualism 4) Alligator and Deer • A lucky alligator spots a deer drinking water, attacks the deer, kills it, and eats it for food. Predation 5) Tapeworm and Dog • The tapeworm feeds off the dogs nutrients. Parasitism 6) Orchids and Trees • Orchids grow on the trunks or branches of the trees. They receive light they need and nutrients that run down along the trees. The orchids do not affect the trees. Commensalism 7) Mildew fungus and Plant • The downy mildew fungus invades a host plant and feeds off it. This often causes discoloration or stunted growth in the plant. Parasitism 8) Clownfish and Sea Anemone • The clownfish lives within the tentacles of the sea anemone. This provides protection to the clownfish and the clownfish also feeds on the food scraps of the sea anemone. Commensalism 9) Spider crap and Algae • Spider crabs live in shallow areas of the ocean floor. Greenish-brown algae lives on the crab's back, helping the crabs blend in with their environment, which makes them less noticeable to predators. The algae provided with a good place to live while the crab receives camouflage. Mutualism 10) Goat and grass • A goat munches on the grass in a field for its food. Predation Chapter 2.2 – Interactions Topic: How do species interact? Vocabulary – Use Window Notes: Define and provide an example.
