topic 3

Question 1

Producers

Answer 1

They get energy from chemicals or the sun, and with the help of water, convert that energy into useable energy in the form of sugar, or food. The most common example of a producer are plants.

Question 2

Consumers

Answer 2

is an organism that feeds on plants or other animals for energy. There are four types of consumers; herbivores (plant eaters), carnivores (meat eaters), omnivores (plant and animal eaters), and detritivores (decomposers).

Question 3

Decomposers

Answer 3

A decomposer is an organism that decomposes, or breaks down, organic material such as the remains of dead organisms. Decomposers include bacteria and fungi.

Question 4

Herbivores

Answer 4

An herbivore is an animal or insect that only eats vegetation, such as grasses, fruits, leaves, vegetables, roots and bulbs. Herbivores only eat things that need photosynthesis to live.

Question 5

Omnivores

Answer 5

is an animal that has the ability to eat and survive on both plant and animal matter.

Question 6

Carnivores

Answer 6

A carnivore is an organism that mostly eats meat, or the flesh of animals. Sometimes carnivores are called predators.

Question 7

Predict the effect of a disturbance (such as hunting, habitat destruction ect) to the organisms in a food chain or web

Answer 7

all the animals will be effected because if one dies then the one that eats that one will die and then the one that eats that one and it will become a domino effect. but animals that would be eaten by a bigger animal would have a increase in population

Question 8

Describe how energy is passed on from one organism to the next in a food chain

Answer 8

Energy is passed between organisms through the food chain. Food chains start with producers. … Plants harvest their energy from the sun during photosynthesis. This energy can then be passed from one organism to another in the food chain

Question 9

Apply the 10% rule to determine the amount of energy passed onto the next organism in a food chain

Answer 9

When a plant is eaten by a primary consumer, only 10% of the energy is passed on. The low percentage of transferred energy can be attributed to different reasons like some of the organism not being eaten,

Question 10

Determine the maximum amount of levels a food chain could contain, based on the amount of energy transferred

Answer 10

Calculate the percent of energy that is transferred from the first trophic level to the second trophic level. Divide energy from trophic level one and multiply by 100.
