Consumers
How do consumers get their name?
Animals are consumers because they consume plants or other animals.
How do producers get their name?
Plants are producers because they produce their own food through photosynthesis
Name 3 kinds of decomposers
Fungi, worms, bacteria
What do zebras eat and what eats zebras?
Zebras eat grass and they are eaten by predators like hyenas and lions.
Can an organism be put in more than one food chain? Explain.
Yes because food webs are interacting food chains.
Why do animals eat other animals?
Animals eat other animals to obtain energy and building blocks (nutrients) in order to grow and repair.
acorn, squirrels, hawks... Which one is the producer?
Acorns
What do worms prefer in their soil?
Dead material.
Where does the energy in almost all food come from?
The sun
What is the reason scientists believe dinosaurs all over the world became extinct?
The smoke and fog from wild fires blocked the sun causing the plants to die. Without producers, consumers cannot live.
Which of the following animals would be considered a secondary consumer? chipmunk, hawk, gorilla
Hawk
What is the chemical process called in which producers create their food?
Photosynthesis
What is released into the air when dead things are decomposed?
Carbon
When a frog eats a grasshopper, how much of the grasshoppers energy does it consume?
10%
How are mushroom roots different from plant roots?
Mushroom roots decompose, or break down dead material, plant roots do not.
What is an example of an apex predator?
Examples will vary.
What would happen if we put tape on a plant's leaves?
Carbon dioxide wouldn't be able to come into the stomata of the leaf.
What roles do worms, fungi, and bacteria play in a food web?
They recycle matter, by breaking down dead and decaying matter. They turn it into nutrients in the soil, which plants use. If ecosystems didn’t have decomposers, dead plants and animals would just pile up.
Draw a 3 step food chain beginning with the sun.
Answers will vary
How is a dinosaurs food chains similar to our food chains?
They all end with a producer.
Why are apex predators critical for an ecosystem?
An apex predator is an animal that feeds on other animals but is at the top of the food web, meaning that it has no predators. Apex predators help control the balance of an ecosystem by keeping the populations of other animals in check.
What is the correct formula for photosynthesis?
Sun+water+carbon=sugar
How are worms the better decomposer?
Their excretions are 10x more nutritious than regular soil.
In a Mississippi swamp, alligators and great blue herons eat fish. What type of organism id a great blue heron, a carnivore, herbivore, or decomposer?
Carnivore
What are some human interactions that could effect a food web?
Humans over-hunting predators such as wolves can lead to a boom in the population of their prey (deer). This can lead to all those deer eating too much grass. Also, when humans cut down trees (deforestation), soil can erode more easily, affecting fish in streams and rivers. When the population of any of these animals are impacted, so are the animals that eat them. It’s all a delicate balance.
