1
Q

Explain what ecology is.

A

the study of the interactions between organisms and their environment

2
Q

What is biotic?

A

living factors like predators, food, pests, other animals, trees

3
Q

What is abiotic?

A

long living factors like water, weather, nutrients in soil

4
Q

What is abundance?

A

a count of the population size.

5
Q

What is distribution?

A

where the organisms are in the environment

6
Q

What is population?

A

all the members of one species living in an area

7
Q

What is community?

A

multiple populations of different species in a specific area

8
Q

what is ecosystem?

A

the living organisms that interact with the abiotic and biotic factors

9
Q

What is nutrients cycling?

A

Nutrients are recycled like when an animal eats an organism and then the animal dies the nutrients are returned to the ecosystem

10
Q

What is energy flowing through an ecosystem?

A

sun gives energy. plants receive it. animal eats plant. animal releases energy. Not recycled.

11
Q

What are producers?

A

Plants. Autotrophs.

12
Q

What are primary consumers?

A

Herbivores that eat plants. Heterotrophs

13
Q

What are secondary consumers?

A

Heterotrophic animals that eat animals

14
Q

What are tertiary consumers?

A

they eat secondary consumers

15
Q

Why are decomposers important in an ecosystem?

A

They eat dead plants and animals, release the nutrients back into the environment

16
Q

what is a trophic pyramid?

A

It is different trophic levels. Like producers, primary consumers and secondary consumers

17
Q

why is a trophic pyramid shaped the way it is in terms of energy availability?

A

Because there’s more producers than primary consumers etc. Energy is lost with each trophic level. Therefore, there’s more energy at the bottom of the pyramid.
