Ecology Review

Midterm Material


Ecology review

Begin on Page 10

Which of the following do you see? Explain why you think you see it.

Ecosystem

Decomposer

Habitat

Water cycle

Biotic factors

Abiotic factors


Ecology review

Ecosystem:

a pond environment is a particular environment,

turtles,trees and grass are living things,

and rocks, water, and air are nonliving things that support these three living things


Ecology review

Decomposers

There aren’t any visible organisms breaking down dead plants or animals.

We do know they are there but we can’t count them because we don’t see them. The question asked us which do we see.


Ecology review

Habitat:

The water is the physical place the turtles live in

and the pond shore is the physical place the trees and grass live.


Ecology review

Water cycle:

Collected water, like a pond, is part of the water cycle but we aren’t able to see the movement of water through the environment.


Ecology review

Biotic Factors:

The turtle, trees and grass are living things

Abiotic Factors:

The rocks, soil, water, and air are nonliving things



Ecology review

Temperature

Light

Soil

4) Water



Ecology review

WE CAN START AT ANY STEP BECAUSE A CYCLE IS STEPS THAT REPEAT!!!!!!

Precipitation: water drops fall because gravity pulls them

Run off / Collection: Water moves downhill, soaks into the ground, or collects in bodies like lakes and ponds


Ecology review

Evaporation: REPEAT!!!!!!Water becomes a gas

Condensation: Water turns back to liquid drops and clings to particles in the air



Ecology review

Predators hunt their food. REPEAT!!!!!!

Only some consumers hunt.

Some consumers eat plants so they don’t hunt.



Ecology review

A food web is made of at REPEAT!!!!!!least two food chains. See page 27



Ecology review

They show food energy flowing through an ecosystem similar?

They show the relationship between producers and consumers



Ecology review

It shows the amount of energy passed up to each level webs DO NOT?

It shows there is less food energy available as one moves up the pyramid. Energy decreases.



Ecology review

A webs DO NOT?niche is a role that an organism has within a habitat

A habitat is where the organism carries out its niche-where it “does its thing”.



Ecology review

A population is PART of a community. webs DO NOT?

A community contains more than one population .



Ecology review

An ecosystem webs DO NOT?contains a community. The community is only the LIVING part of the ecosystem. There is also a nonliving part in an ecosystem.



Ecology review

A pattern in space pattern in space?:

Examples are-

*Dancers on a stage

*Sports players-football, volleyball,

soccer, etc

*People sitting at cafeteria tables

*Animals in a herd

*Fish in a school

*Geese in flight
