Map Test Review - Set 7

Front 1

Plants and animals and nonliving things in a particular location together are called an _____________________

Back 1

Ecosystem

Front 2

The living things in an ecosystem (plants, animals, bacteria, fungi, mircroorganisms) are called the ________________ factors in that ecosystem.

The nonliving factors in an ecosystem (rocks, water, logs, soil, etc) are called the ______________ facotrs

Back 2

Biotic

(biotic factors are the living things in an ecosystem)

Abiotic (abiotic factors are the nonliving things in an ecosystem)

Front 3

Groups of specific plants and animals that live together in an ecosystem are called a ______________________.

Back 3

Population

(A population is all the individuals of a given species in a specific area at a specific time).

Front 4

In an ecosystem, there are many food ____________ that show how different organisms eat each other starting with a plant and ending with an animal.

Back 4

Chains

(food chains show how different organisms eat each other starting with a plant and ending with an animal)

example: grass --> zebra ---> lion

Front 5

All the food chains together creates a food ___________, which is a system of interconnected and interdependent food chains.

Back 5

Webs

(most plants and animals are part of several food chains. when you draw all the food chains together, you get a food web)

Front 6

Describe the carbon cycle:

Back 6

Carbon is extracted from the atmosphere by plants (who use it for photosynthesis). The carbon is later transferred to animals who eat the plants. When plants and animals die, the carbon is returned to the atmosphere, or some of it may be trapped where decomposition can't take place. The amount of carbon trapped is about the same as that in the atmosphere so there is a balance. This is the carbon cycle.

Front 7

How can the delicate carbon balance be upset?

Back 7

One idea is that the overuse of fossil fuels may lead to more carbon being in the atmosphere than is trapped beneath earth's surface. This could possibly lead to an imbalance in the carbon cycle.

Front 8

Describe the Oxygen Cycle:

Back 8

21% of our atmosphere is made of oxygen. Plants add oxygen to our atmosphere and animals remove it by breathing it in and using it. At the same time, plants need carbon dioxide that animals exhale back into the atmosphere.

Front 9

Together, the Carbon Cycle and the Oxygen Cycle make up the ________ __________ Cycle

Back 9

Carbon-Oxygen Cycle

Front 10

When the remains of plants and animals were covered by sediment like mud or sand and the parts didn't rot away (like bone, teeth, shell, etc) and became encased in the sediment, sometimes, in the right circumstances, parts of the plants and animals turned into ___________ over time.

Back 10

Fossils

Front 11

Name the four types of fossils:

Back 11

1. Mold Fossils (fossilized impressions of organisms)

2. Cast Fossil (created when impressions were filled in)

3. Replacement Fossils (rocklike minerals seep in and replace the original hard part of an organism , like bone, teeth, shell, wood, etc)

4. Preservation Trace Fossils (fossils that show past activities of organisms - like tracks, nest, burrows, etc)

Front 12

The fossilized impression of an organism is called a ____________________ fossil.

Back 12

Mold

Front 13

When impressions of organisms (molds) are filled in with sediment and harden over time, a ____________ fossil can be formed.

Back 13

Cast

Front 14

When rocklike minerals seep in and replace the original hard part of an organism (bone, teeth, shell, wood, etc) a special kind of fossil called a ______________ fossil is formed. (examples would be things like petrified wood)

Back 14

Replacement

Front 15

One type of fossil that occurs includes the fossilized evidence of past activities of organisms (tracks, burrows, nests, etc). These are called _________________________ fossils.

Back 15

Preservation Trace

Front 16

By studying fossils and the fossil ____________, we can tell how long life has existed on Earth and how different plants and animals are related to each other.

Back 16
