Ecology Review

Midterm Material

slide2

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

slide3

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

slide4

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.

slide5

Habitat:

The water is the physical place the turtles live in

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

slide6

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.

slide7

Biotic Factors:

The turtle, trees and grass are living things

Abiotic Factors:

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

slide9

Temperature

Light

Soil

4) Water

slide11

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

slide12

Evaporation: Water becomes a gas

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

slide14

Predators hunt their food.

Only some consumers hunt.

Some consumers eat plants so they don’t hunt.

slide18

They show food energy flowing through an ecosystem

They show the relationship between producers and consumers

slide20

It shows the amount of energy passed up to each level

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

slide22

Aniche 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”.

slide24

A population is PART of a community.

A community contains more than one population .

slide26

An ecosystem contains a community. The community is only the LIVING part of the ecosystem. There is also a nonliving part in an ecosystem.

slide28

A 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
