Unit 1: Ecology Flashcards
Learn about different ecosystems and food chains and food webs.
What is an ecosystem?
a community of living and nonliving things in their natural environment
What is a decomposer?
They eat decaying matter (dead plants and animals). The decomposer breaks this matter down and release nutrients and minerals back into the soil.
What is a Food Chain?
A path of energy from one organism to another
What is a producer?
They make their own food using energy from the sun, air, and water
What is an earthworm’s role in the ecosystem?
A. A consumer because it’s an animal.
B. A producer because it makes it’s own food.
C. A decomposer because it breaks down small dead organisms.
D. A producer because it eats an apple.
E. None of the above
C
What is a consumer?
They eat another living thing (plant or other animals) for energy
What is a Venus flytrap’s role in an ecosystem?
A. A decomposer because it breaks down dead insects
B. A producer because it makes it’s own food.
C. A producer because it is a plant.
D. A consumer because it makes it’s own food.
E. None of the above
The correct answer is E. It’s e because consumers don’t make their own food, and it is a plant, but it eats animals.
What is a food web?
An interconnected set of food chains
Suppose people are spraying pesticides on grass. What will happen to the animals that eat grasshoppers?
The animals won’t have as much of a food source, because the grasshoppers don’t have the grass they need to eat.
What does over-abundent mean?
When there is an excess or a lot of one organism or food supply.
Part A: What can you infer about how the wolves population increased in the 90s?
Part B: What do you think will happen if elk aren’t there for wolves to eat?
Part C: What supports your answer from Part B?
A: They will have a lot of food, which is why they will increase.
B: They will decrease, because they don’t have enough food.
C: They will eat each other.
D. All of the above
Part A: I infer the wolves’ population increased in the 90s because they were not getting eaten or hunted as much.
Part B: The wolves’ population will decrease.
Part C: B
Perish
To die
Survive
To stay alive
Scarce
When there is not much of one organism or food supply
Extinct
No Longer Existing. (Like Leif’s Hair/)
