Croft’s Way to Make a 100/A
Chapter 24
Woodpeckers use their beaks to pry insects from trees is their niche.
Monarch butterflies eat milkweed, making them poisonous to other species is an example of its niche.
A male lion’s mane attracts a mate is its niche.
Ducks and amphibians live in or near a pond is its habitat.
A chameleon changes its colors to blend in with its surroundings is its niche.
A puppy that has a tapeworm in her stomach is an example of parasitism.
A clown fish being protected by an anemone’s tentacles is an example of commensalism.
Consumers eat producers in the wild.
Producers use the sun to make their own energy (food).
Decomposers consume waste and dead organisms.
Ecology is the study of interactions among organisms and their environment.
Symbiosis is any close relationship between 2 species.
A consumer is an organism that cannot make its own energy.
The maximum rate of increase for a population is its biotic potential.
The desert would be a tarantula’s habitat.
Ecologists are scientists that study organisms in their environment.
A tree is a producer.
When there are more births than deaths in a population, that usually increases the size of the population.
Parasitism is a symbiotic relationship in which one species is helped and the other is harmed.
Which of the following organisms is an example of a herbivore? Wolf, flower, tree, rabbit
The number of individuals in a population that occupies an area of a specific size describes its density.
Which of the following is a living factor in the environment? Animals, air, sunlight, soil
When a deer alerts other deer in a herd that there is a wolf coming this is an example of cooperation.
Little food, not enough space, and not enough females for mating would be limiting factors in a population of
zebras.
An individual is a single living organism, such as one snake.
Plants are always at the beginning of a food chain.
A buffalo and an oxpecker (small bird that sits on the buffalo’s back) have a mutualistic relationship.
A seal and a fish have a predator/prey relationship.
A tapeworm and a dog have a parasitic relationship.
An owl and a mouse have a predator/prey relationship.
Consumers that eat only animals are called carnivores.
Consumers that eat only plants are called herbivores.
Producers are always the start of a food chain.
Consumers that eat both plants and animals are called omnivores.
Decomposers break down waste material and dead animals to get energy.
A relationship in which 2 organisms live together and both benefit is called mutualism.
When an owl and a fox live in the same community where there are very few mice, the owl and fox become
competitors.
In the relationship between a bird and a worm, the bird is the predator.
All of the following are a part of a species niche: how it interacts, what it eats, and how it gets food.
The place an organism lives in a community is its habitat.
Population characteristics include density, size, and spacing.
A population is organisms of 1 kind of species that live together.
The largest number of individuals an environment can support is called its carrying capacity.
The study of interactions between organisms and the things in their environment is called ecology.
Any factor that restricts the number of individuals in a population is called a limiting factor.
An ecosystem is a community interacting with the abiotic factors of their environment.
All the populations of different species that live in the same place at the same time are called a community.
The number of individuals in a given area is called a population density.
The biosphere is the part of Earth where life is found.
