There are levels of organization in an ecosystem:

Abiotic Factors  Non-living factors in an ecosystem  Include water, air, light, minerals, soil, temperature, and climate. Biotic Factors  All living.

An ecosystem is made up of a community of organisms and the non-living environment. The living components of the ecosystem are called biotic factors, which.

Ecological Pyramids Graphical models of the quantitative differences that exist between trophic levels of a single ecosystem. They can be pyramids of numbers, biomass, or productivity.

the accumulation of substances, such as pesticides, Ecology Students will be able to: -Define the term trophic level and identify and explain trophic levels in food chains and food webs. -Explain the principles of pyramids or numbers, pyramids of biomass and pyramids of productivity, and construct such pyramids from given data. -Discuss how the pyramid structure affects the functioning of an ecosystem. -Define the following population interactions and relate them to real world examples: neutralism, ammensalism, mutualism, commensalism, and parasitism. Bioaccumulation = the accumulation of substances, such as pesticides, or other organic chemicals in an organism.

Population interactions occur in 5 main ways. Interspecific competition When members of two or more species interact to gain access to the same limited resources. Ex. Food, light, or space. Predation - occurs when a member of one species feeds directly on all or part of a member of another species. Parasitism occurs when one organism feeds on the body of, or the energy is used by, another organism, usually by living on or in the host. Mutualism is an interaction that benefits both species by providing each with food, shelter, or some other resource. Commensalism an interaction that benefits one species but has little, or no, effect on the other.
