Freshwater
Freshwater food web
The sun is the source of all energy. Some of the producers in this food web are:
Zooplankton, Bacteria, Phytoplankton, and Algae. A few of the consumers are bass, mayfly, and trout. The tertiary consumer of this web is the heron.
Commensalism
Relationship between two organisms in which one partner benefits, while the other does not receive any benefits or harm.
Mutualism
The biologic association of two individuals or populations of different species, both of which are benefited by the relationship.
Parasitism
A symbiotic relationship in which one species, the parasite, benefits at the expense of the other, the host.
How humans affect the environment
An increase in population makes excessive demands on natural resources, and increases the demand on agricultural and live stock. Using chemicals, fertilizers, and insecticides to increase population actually pollute the air and water. Removing trees and other plants to increase areas of cultivation causes habitat loss.
3 organisms
For my 3 organisms I choose a heron, bass, and zooplankton. The heron is the territory consumer, the bass is a consumer, the zooplankton is a producer, and bacteria is the decomposer. The heron eats the bass, the bass eats the zooplankton, the bacteria is the decomposer.
