Environmental Science (For Test)

Question 1

what is another word for living things in an Ecosystem?

Answer 1

Biotic elements.

Question 2

What is another word for non-living things in an Ecosystem?

Answer 2

abiotic element.

Question 3

Biotic elements have five basic needs for survival. What are they?

Answer 3

1. oxygen
2. water
3. food
4. energy
5. suitable habitat (place to live)

Question 4

What processes do the producers use to make food?

Answer 4

photosynthesis

Question 5

What are the three roles the producers have in an ecosystem?

Answer 5

1. They produce oxygen.
2. They supply food.
3. They provide shelter.

Question 6

List two ways the Sun supports life.

Answer 6

heat and light

Question 7

Explain why photosynthesis is important

for ecosystems everywhere.

Answer 7

because they produce all of the original chemical energy in the ecosystem.

Question 8

What are the three types of consumers?

Answer 8

1. Herbivores
2. Carnivores
3. Omnivores

Question 9

What do herbivores eat?

Answer 9

Plants

Question 10

What do Carnivores eat?

Answer 10

Meat

Question 11

What do Omnivores eat?

Answer 11

Both (Plants and Meat)

Question 12

Define Prey

Answer 12

An animal that is hunted for food

Question 13

Define Predator

Answer 13

The animal that hunts and consumes

the prey

Question 14

What are the three Special Consumers?

Answer 14

Scavengers, Detritivores, and Decomposers

Question 15

Define Scavengers

Answer 15

Scavengers are consumers that do not usually kill
their own food. Instead, they feed off the remains of dead animals.Crows, ravens, and housefly larvae
(maggots) are examples of scavengers.

Question 16

Define Detritivores

Answer 16

Detritivores are consumers that feed off waste. Snails and earthworms are common examples
of detritivores.

Question 17

Define Decompose

Answer 17

Decomposers are consumers that break down
(decompose) dead plants and animals into smaller pieces.
Fungi, such as mushrooms and mould on bread, fruits, and vegetables, are decomposers.

Question 18

What is the main difference between a

producer and a consumer?

Answer 18

Producers are capable of photosynthesis, a process by which they convert light energy into chemical energy, while consumers use respiration

Question 19

What is an ecosystem?

Answer 19

An ecosystem is a large community of living organisms (plants, animals, and microbes) in a particular area

Question 20

What are the 4 types of an ecosystem?

Answer 20

artificial (Human-made: Zoo), terrestrial (land-based: tundra, forests), lentic (non-flowing water: lake, pond, swamp) and lotic (flowing water: river)

Question 21

Define Biome

Answer 21

A biome can be made up of many ecosystems.

Question 22

What are the 7 main biomes?

Answer 22

tropical rainforests, temperate forests, deserts, tundra, taiga, grasslands, and savanna

Question 23

Producers vs Consumers Vs Decomposers

Answer 23

Producers can make their own food by capturing the sun’s energy.

Consumers need to eat other organisms to obtain energy

Decomposers are like the recyclers of nature. A decomposer is an organism that decomposes or breaks down, organic material such as the remains of dead organisms

Question 24

What are some abiotic parts in an environment?

Answer 24

sunlight, temperature, wind, water, soil

Question 25

What are some biotic parts in an environment?

Answer 25

plants, animals, and micro-organisms.

Question 26

What do plants use to make their food?

Answer 26

Carbon Dioxide, Water, and Sunlight

Question 27

What is Population?

Answer 27

Populations are groups of individuals that belong
to the same species and live in the same area at the
same time.

Question 28

What is Community?

Answer 28

A community is made up of populations of

different species that live and interact in a habitat.
