Without the sun’s energy, all living things would die. Especially in the tropical rainforest the sun is essential for survival. Without the sun, plants would not survive and life as we know it would cease to exist. (Choi, 2012). As an alternate form of energy, plants will use the sun, chlorophyll, water, carbon dioxide and nutrients in order to manufacturer glucose. (UCSB Science Line).

The ecosystem must have some type of external energy. (Regoniel, 2014). Solar energy is used to produce organic plant material through photosynthesis. Animals that feed solely on plants make up the second trophic levels which are called herbivores. The third trophic level are predators that will eat herbivores. Solar energy is essential for an ecosystem. Plants use solar energy and converts that energy into other energy sources that animals could use. (Ellis, 2014).
An ecosystem is a community of different species interacting with each other and their environments. (Cunningham, 2013). Water, air, nutrients, solar energy, living plants, animals and microbes are the major components of ecosystems. If you take away any one of these components, the ecosystem fails.
A basic example of how an ecosystem works is as follows (Regoniel, 2014):
* Consumers feed on organisms
* Decomposers break down resources into simple compounds
* Omnivores feed on both plants and animals
* Carnivores feed on the animals
* Detritivores feed on the dead omnivores and carnivores
* Herbivores feed on plants
* When all of the above die, they break down and go back into the ecosystem
