What process do plants use to make their own food?
Photosynthesis.
What green substance in leaves traps light for photosynthesis?
Chlorophyll.
Where do plants get the light energy needed for photosynthesis?
The Sun.
Can animals make their own food?
No.
What is an animal that hunts and eats another animal called?
A predator.
Why do plants need chlorophyll?
Chlorophyll traps light energy needed for photosynthesis.
A rabbit eats grass to get energy. Is the rabbit a producer or consumer?
Consumer.
A hawk catches and eats a mouse. Which animal is the predator?
The hawk.
A plant gets energy from sunlight, while a cow gets energy by eating grass. What is the main difference?
The plant makes its own food using light, while the cow gets energy by consuming food.
Why are animals called consumers?
Because they get energy by consuming plants or other animals.
A plant is placed in a dark cupboard for several days. What might happen to its ability to make food? Why?
Its ability to make food will decrease because it needs light for photosynthesis.
A seagull catches and eats a fish. Identify the predator and the prey.
Answer: The seagull is the predator, and the fish is the prey.
A rabbit eats grass in a field. The rabbit does not make food from sunlight. How does the rabbit get energy?
It gets energy by eating the grass.
wo identical plants are given the same amount of water. Plant A receives sunlight, while Plant B is kept in darkness. Which plant can continue photosynthesis more effectively? Explain.
Plant A, because it receives light needed for photosynthesis.
An eagle eats a snake, and the snake eats a mouse. Which animal is the predator of the mouse?
The snake.
A student says, “Plants eat sunlight because sunlight gives them energy.” Do you agree? Explain what actually happens.
No. Plants do not eat sunlight. Their leaves use light energy, along with water and carbon dioxide, to make food through photosynthesis.
A mouse eats seeds, and an eagle eats the mouse. Explain why the mouse can be both a consumer and prey.
The mouse is a consumer because it eats seeds, and it is prey because an eagle hunts and eats it.
A rabbit eats a plant, while the plant uses sunlight to make food. Explain how the rabbit ultimately gets energy from the Sun.
The plant captures energy from sunlight during photosynthesis. The rabbit eats the plant and obtains some of that stored energy.
A fox and a rabbit are in the same field. The fox hunts the rabbit, while the rabbit eats grass. Explain why the fox and rabbit have different roles in the food relationship.
The rabbit is a consumer that eats plants and is prey to the fox. The fox is a predator because it hunts and eats the rabbit.
A plant has plenty of water but very little light. Another plant has plenty of light but very little water. Explain why both plants may have difficulty making food.
Both light and water are needed for photosynthesis. A shortage of either can limit the plant's ability to make food.
Imagine a plant is placed inside a completely dark room but receives plenty of water. Predict what will happen to its food production and explain why.
Food production will greatly decrease because the plant needs light energy for photosynthesis. Water alone is not enough.
A caterpillar eats leaves, and a bird eats the caterpillar. If the number of leaves decreases greatly, predict how this could affect the bird.
There may be fewer caterpillars because there is less food for them. As a result, the bird may have less prey available.
In a grassland, grass is eaten by rabbits, and rabbits are eaten by foxes. If there were no grass, explain how this could affect both rabbits and foxes.
Rabbits would have less food and their population could decrease. Foxes could then have fewer rabbits to hunt.
A student says, “The rabbit gets its energy directly from the Sun because it eats plants.” Is this statement correct? Explain your reasoning.
No. The rabbit gets its energy by eating plants. The plant first captures light energy from the Sun and stores it in food.
Create a simple food relationship using one plant, one herbivore and one predator. Explain how energy moves through the three organisms.
The grass uses sunlight to make food. The rabbit eats the grass and gets energy from it. The fox eats the rabbit and gets energy from the rabbit.
