Producers make their food. They use a process called photosynthesis to make their food. Photosynthesis uses which of the following ingredients
water, sunlight, soil
water, air, sunlight
water, sunlight, carbon dioxide
water, soil, air
Explanation
Plants (producers) are at the beginning of every food chain that involves the Sun. All energy comes from the Sun, and plants are the ones who make food with that energy through photosynthesis. Plants get their energy from the Sun, carbon dioxide, and water. Without water transporting nutrients to the plants, they would not grow and survive. Water also helps cool plants as they evaporate water through transpiration.
Which statement best describes how energy is transformed during photosynthesis?
plants take in chemical energy and change it to thermal energy
plants take in light energy and change it to chemical energy in the form of food
plants take in thermal energy and change it to light energy
plants take in chemical energy and change it to light energy
Explanation
Plants are called producers because they produce their food. Through photosynthesis, plants absorb carbon dioxide with their leaves, water, and nutrients from the soil with their roots, and sunlight to create glucose. This energy-rich sugar gives plants what they need to grow and survive. Plants are the only organism that can use sunlight to make their food.
Plants make up most of the Earth's biomass or organic material. What would happen to consumers if there were no more plants?
They would use photosynthesis to make their own food.
They would die because they would have no source of energy.
They would eventually adapt to only eating other consumers.
They would get their energy from other sources, like oxygen.
Explanation
Plants (producers) indirectly provide energy to all members of the food chain. When something consumes a plant and is later eaten, that energy is passed down the line. Decomposers and herbivorous consumers are the only two members that directly receive energy from plants (producers). If plants were removed from the food chain, consumers would die because they would have no source of energy.
Which statement about the flow of energy in an ecosystem is correct?
Energy flows from the Sun to consumers. Producers get energy by eating consumers.
Energy flows from the Sun to decomposers. Consumers get energy by eating decomposers.
Energy flows from the Sun to producers. Consumers get energy by eating producers.
Energy flows from the Sun to decomposers. Producers get energy by eating decomposers.
Explanation
Plants (producers) indirectly provide energy to all members of the food chain. When something consumes a plant and is later eaten, that energy is passed down the line. Decomposers and herbivorous consumers are the only two members that directly receive energy from plants (producers). Energy flows from the Sun to producers. Consumers get energy by eating producers. The flow of energy starts with the Sun, flows to producers, and then to consumers. The decomposers break down the organisms that are no longer living and return that energy to the Earth.
What member of the food chain directly receives energy from plants in a food chain?
Decomposer
Top carnivore
2nd level carnivorous consumer
The Sun

What is a plant called in a food chain?
A producer
A decomposer
A top carnivore
A herbivorous consumer
Explanation
Plants are called producers and are a vital part of the food chain. This food chain is based in the ocean and features all aquatic organisms. Plants get their energy from the Sun and water. Without water transporting nutrients to the plants, they would not grow and survive.
Which consumers in the model indirectly receive energy from producers?
1st level carnivorous consumers, 2nd level carnivorous consumers, 3rd level carnivorous consumers, and top carnivores
2nd level carnivorous consumers, 3rd level carnivorous consumers, and top carnivores
Decomposer, herbivorous consumers, and the Sun
Decomposer, 1st level carnivorous consumers, herbivorous consumers, and the Sun
Explanation
Some members of the food chain receive energy from plants directly, and others receive it indirectly. 1st level carnivorous consumers, 2nd level carnivorous consumers, 3rd level carnivorous consumers, and top carnivores all receive a plant's energy second-hand because they are eating something (like a herbivorous consumer) that has previously eaten a plant. Anything that is a carnivore only eats meat, so it will not directly consume a producer.
What is the process called by which producers create their food?
Photosynthesis
Autosynthesis
Aquasynthesis
Hyoersynthesis
Explanation
Plants (producers) are at the beginning of every food chain that involves the Sun. All energy comes from the Sun, and plants are the ones who make food with that energy through photosynthesis. Plants get their energy from the Sun and water. Without water transporting nutrients to the plants, they would not grow and survive. Water also helps cool plants as they evaporate water through transpiration.
Why are plants called producers in the food chain?
They make their own food.
They catch their food.
They produce energy for the Sun.
They produce homes for many insects.
Explanation
Plants are called producers because they produce their food. Through photosynthesis, plants absorb carbon dioxide with their leaves, water and nutrients from the soil with their roots, and sunlight to create glucose. This energy-rich sugar gives plants what they need to grow and survive. Plants are the only organism that can use sunlight to make their food.
Plants and animals need energy to survive. Which of the following statements are correct?
Energy in animals is passed to plants.
Animals can make the energy they need.
Energy flows from producers to consumers.
Some food chains have only consumers.
Explanation
Energy flows from producers to consumers. Plants (producers) indirectly provide energy to all members of the food chain. When something consumes a plant and is later eaten, that energy is passed down the line. Decomposers and herbivorous consumers are the only two members that directly receive energy from plants (producers). The food chain relies on each member to pass energy on to the next. If one link in the chain is broken, the food chain will collapse.
