Use the Food chain
100

Animals who primarily eat plants

Herbivores

100

Animals who primarily eat meat

Carnivores

100

This will happen to the number of prey in an ecosystem if the number of predators increases

Decrease

100

This organism is the most important part of the energy pyramid/food web for transferring energy to other organisms.

Producers

100

organisms that eat both plants and animals

Omnivores

100

Grass → Mouse → Snake → Hawk 


Which organism is the producer?

Grass

200

All the organisms in an area and the environment they live in

An ecosystem

200

Organisms that eat other animals and plants for energy

Consumers

200

This is what the arrows in a food chain represent

Energy transfer

200

This level of consumers are usually herbivores

Primary consumers

200

This is an example of a decomposer

Mushroom, worm, mold/fungus or bacteria

200

Grass → Mouse → Snake → Hawk 


Which organism is the secondary consumer?

Snake

300

Organisms that produce or create their own food/energy

Producers

300

Process where plants take in water, carbon dioxide, and sunlight to produce energy and oxygen.

Photosynthesis

300

This is the difference between food chains and food webs

Food chains show energy transfer between single organisms while food webs show energy transfers between food chains (many of the organisms in an ecosystem)

300

This level of consumers are usually medium omnivores

Secondary consumers

300

These 2 items are what plants produce when they go through photosynthesis

Oxygen and energy (sugar)

300

Which organism is the primary consumer?

Mouse

400

The transfer of energy between single organisms

Food chain

400

Shows energy transfer between food chains

Food web

400

This is the reason decomposers are important to the ecosystem

They break down dead organisms which provides space and nutrients for new organisms to grow

400

This level of consumers is usually large carnivores/predators

Tertiary Consumers

400

Green pigment in leaves which allows plants to absorb sunlight for energy

Chlorophyll

400

Which organism is most essential for the survival of the rest of the organisms, without it the rest of the foodchain will die?

Grass

500

 What PH level shows that water is neutral? (number)

7

500

Organisms that break down dead organisms to get their energy

Decomposers

500

This is what would happen to the food chain if the producer was wiped out or died

Each level of consumer from primary to tertiary would no longer have a food source and the food chain would collapse

500

This is how much energy is passed from one organism to another when it is eaten (as a percentage)

10%

500

These 3 things are needed for plants to take in in order to perform photosynthesis

Sunlight, water, and carbon dioxide

500

2 parts- Must get both parts correct


1. What classification of organism is responsible for recycling nutrients in the ecosystem?

2. What is the main source of energy for the entire ecosystem --> This starts where ALL organisms in the ecosystem get their energy 

1. Decomposers

2. The Sun. The Sun gives energy through light to producers. No sun = no energy for producers. No producers = no ecosystem
