Define the different forms of community interaction: competition, commensalism, mutualism, predation, parasitism Give an example and a picture for each

Community interactions are factors that can have a huge affect on an ecosystem. In competition, organisms of the same or different species try to use ecological resources,necessities to life, at the same place and time. For example, oak trees compete with other trees for sunlight. As their leaves spread out, they block sunlight for the shorter trees. In competition, they have to follow the competitive exclusion principle,where two species can not use the same resources at the same place and place. Resources must be founded in different areas.

Also, Predation is when an interaction in which one organism captures and feeds on another organism. The organism that captures and feeds is the predator. The organsim being eaten is the prey.An example of predation would be a lion using his characteristic such as strong  legs, sharp claws and teeth to aid him in killing other animals.

In addition, symbiosis is any relationship of two species living closely together. Symbolism is divided into three class: mutalism, commenalism,parasitism. In mutualism, both species benefit from living together. For example, flowers depend on bees to help spread their pollen or nector so the plants can reproduce. In commenalism, one benefits and the other is neutral.Barnacles attach themselves to whales to attain food as the waters pass by without harming  the whale in any whale. Finally, in parasitiam one organism lives on or inside another organism and harms it. The parasite uses a host to attain nutrients. Fleas, ticks, lice, and tapeworms are examples of paratism eating the host's blood and skin.
