A food web is a type of graph that depicts the relationship between the prey and the predators‚ also known as a system of food chains and how one another are related. This can be better explained as a connection in a community. Food webs are important because it is a direct illustration of the relationships among certain species within a certain community.

According to the 1992 United Nations Earth Summit in Rio Janeiro‚ biodiversity may be defined as‚ “the variability among living organisms from all sources including‚ inter alia‚ terrestrial‚ marine and other aquatic ecosystems and the ecological complexes of which they are a part. Although tropical forests Cover only six percent of Earth’s land surface; it is alleged that they contain between 70% and 90% of the world’s entire species. It has been documented that as

Introduce this section with the food chain discussion card called ‘Under the sea’. Food chains are a flow of energy Food webs exist in a delicate balance. If one animal’s source of food disappears‚ perhaps from a natural cause such as a drought or a killer disease‚ many other animals in the food chain are affected. Some populations may decline‚ and some explode. Humans are usually at the top of the chain and are often responsible for disrupting food webs. All living things depend

Three characteristics of the structure of a community/ecosystem are physical appearance‚ species diversity‚ and niche structure. Species diversity consists of the combination of a number of different species‚ called species richness‚ and the abundance of members in each species‚ called species evenness. 4. Latitude
