Question 1

Producers

Answer 1

An organism that uses an outside energy source, such as the sun, and produces its own food.

Question 2

Consumers

Answer 2

An organism that cannot make its own food and gets energy by eating other organisms.

Question 3

Detritivores

Answer 3

An organism that consumes the bodies of dead organisms and wastes produced by living organisms.

Question 4

Food chain

Answer 4

A model that shows how energy flows in an ecosystem through feeding relationships.

Question 5

Food web

Answer 5

A model of energy transfer that can show how the food chains in a community are interconnected.

Question 6

Herbivore

Answer 6

An organism that only consumes plants.

Question 7

Omnivore

Answer 7

An organism that consumes both plants and animals.

Question 8

Carnivore

Answer 8

An organism that consumes only animals.

Question 9

All food chains and food webs begin with a producer.
Producers harness the energy from the sun to carry out photosynthesis and produce their own food. They are typically plants.
The next organism in a food chain is a primary consumer. Primary consumers are either herbivores or omnivores.
Next are the secondary consumers which are omnivores or carnivores.
Tertiary consumers are typically apex predators and mostly carnivores.

Question 10

Energy Pyramid

Answer 10

A model that shows the amount of energy available in each link of a food chain.

Question 11

In an energy pyramid, there is approximately 10% of the energy from the previous level available. This is because the organisms use the rest of their energy to carry out their living processes such as cellular respiration, reproduction, growth etc.

Question 15

what are producers

Answer 15

an organism that makes its own food

Question 16

what are primary consumers

Answer 16

an organism that eats plants or algae

Question 17

secondary comsumers

Answer 17

an organism that gets its energy by eating primary consumers, which are usually herbivores

Question 18

what are tertiary consumers

Answer 18

an organism that eats other animals, including secondary consumers, and is typically found at the top of a food chain
