They can reproduce on their own and their shapes can be round, rod like, spiral, or filamentous. The fungus organisms lack Chlorophyll and therefore depend on other organisms for food. This section contains a brief description of the food chains and food webs in an ecosystem . In an ecosystem, plants capture the sun's energy and use it to convert inorganic compounds into energy-rich organic compounds 1 .
Photosynthesis is only the beginning of a chain of energy conversions.
There are many types of animals that will eat the products of the photosynthesis process. Examples are deer eating shrub leaves, rabbits eating carrots, or worms eating grass. When these animals eat these plant products, food energy and organic compounds are transferred from the plants to the animals. These animals are in turn eaten by other animals, again transferring energy and organic compounds from one animal to another. Examples would be lions eating deer, foxes eating rabbits, or birds eating worms.
