Pyramid of NumbersShows the relativenumber of individualorganisms at eachtrophic level.
Biomass PyramidRepresents the amount ofliving organic matter at each trophic level. Typically, thegreatest biomass is at the base of the pyramid.
Energy PyramidShows the relative amount of energy available at each trophic level. Organisms use about 10 percent of this energy for life processes. The rest is lost as heat.

Pollution can be chemicals, nutrients, conditions, or structures that are harmful.
Its amazing just how large a problem this can be!

Eutrophication is the gradual filling in of bodies of water through the build up of sediment.
How would an algae bloom affect this?

Use Less Heat and Air Conditioning Change a Light Bulb
Drive Less and Drive Smart
Buy Energy-Efficient Products
Use Less Hot Water
Use the "Off" Switch Plant a Tree
Get a Report Card from Your Utility Company
Encourage Others to Conserve
Use less harmful substances.

Some things like mercury are bioaccumulative.
It becomes moreconcentrated as you go up the food chain.
How can you reduce this problem?
