Plants don't make their own food.
False
What is the main product of photosynthesis?
Sugar
In photosynthesis, carbon dioxide is transformed into?
Oxygen.
What is a food chain?
A food chain is a path by which energy flows from one living thing to another in an environment.
What source of energy do plants use to make food?
Plants use the energy of sunlight to make their own food.
What materials do plants use to make food?
Carbon dioxide and water
Where is chlorophyll found?
In the leaves.
What chemical allows plants to capture the energy in sunlight?
Chlorophyll
What is a producer?
What is a consumer?
They are organisms that make their own food, such as plants.
A consumer is a living thing that eats plants or animals.
Plants that grow on branches of trees are called__________. Give an example.
Epiphytes.
Orchid
How does an orchid in the rain forest get what it needs to survive?
Orchids get sunlight by growing high up in the branches of tall trees. They get water from rain and fog.
What happens during the process of photosynthesis?
Energy from the sun is used to change carbon dioxide and water into sugar and oxygen.
What is another way that warm-blooded animals, such as elephants, use energy?
To keep their bodies warm
What is the difference between a web and a chain?
There is one pathway in a chain, but a web has many different pathways.
What is hydrophonics?
In hydroponics, plants are grown in water instead of soil.
What are some ways that animals use energy from the food ?
To grow larger and to repair their bodies and to move and to carry out other life functions, such as digestion,
How do consumers get their energy?
Consumers get their energy by eating food. Some consumers eat plants, others eat other consumers, and others eat both.
What is the difference between a producer and a consumer?
Producers make their own food, usually by using energy from the sun. Consumers eat other living things for food.
Imagine two different environment and their food chain, a mountain food chain and a pond food chain. What is the original source of energy for both food chains?
The sun.
What is the origin of the word "photosynthesis" and what is its meaning?

Mentions some of today's gowing crops problems.

Pests and too much or too little rain
can harm crops.
Overpopulation. As the population
grows, more and more land will be used for cities,
roads, and homes.
Why is the first organism in a food chain always a producer?
Producers are the only organisms able to capture and use the energy from sunlight to make their own food.
What is the origin of the word "Chlorophyll" and what is its meaning?
Chlorophyll comes from two Greek words. Chloro means “green” and phyll means “leaf.”
How is energy transferred from organism to organism?
The organisms higher on the food chain consume organisms lower on the food chain.
