Photosynthesis and Energy Transfer in Organisms

Plants are autotrophs. Autotrophs use energy to make food Plants are autotrophs. Autotrophs use energy to make food. Plants are autotrophs since they use light energy to make food from water, carbon dioxide (CO2) and nutrients found in water and soil

The Process of Photosynthesis

In the process of photosynthesis, the plant absorbs water, carbon dioxide, and radiant energy from the sun. As a result, glucose and oxygen are produced by the plant.

Glucose is one of the products of photosynthesis in plants Glucose is one of the products of photosynthesis in plants. It serves as a plants main source of energy

How is energy transferred among organisms? Organisms change energy from the environment or from the food they consume in other types of energy.

How does an organism use energy? For activities such as breathing or moving Some energy is stored and saved within the organism to use later

Organisms are classified based on how they get energy Decomposer- An organism that gets energy and nutrients by breaking down the remains of other organisms. Some mushrooms and bacteria are considered decomposers because they break down and convert dead organisms and animal and plant waste into materials such as water and nutrients.

Mushrooms and Bacteria as decomposers

Organisms are classified based on how they get energy Consumer- An organism that eats other organisms. Consumers use the energy and nutrients stored in other living organisms because they cannot make their own food.

There are three types of consumers Herbivore- A consumer that eats only plants. An example of a herbivore would be a grasshopper or bison. Carnivore- A consumer that eats other animals. An example would be a badger or a wolf. Omnivore- A consumer that eats both plants and animals.
