Desert Food Web

The biome I chose is the desert biome. In this biome the producer get all of its energy from the sun. The primary consumers in this biome are the ant, the beetle, and the rat they all feed off of the cacti. The secondary consumers that prey on the primary consumers are tarantulas, scorpions, lizards and the snakes. The tertiary consumers in this biome are the ones that eat the secondary consumers, which are the hawks and coyotes.

Mutualism

this occurs when both organisms benefit from It can be divided into three categories:


Trophic mutualism is when both organisms benefit from the resources.


Dispersive mutualism is when one organism benefits from resources and one receives

services.


Defensive mutualism is when both organisms benefit from services.

Commensalism

refers to the process in which only one organism benefits and the other is neither harmed or helped. This may also be put into three groups:


Phoresy commensalism is when one organism uses the other for transportation.


Inquilinism commensalism happens when one organism uses the other for shelter.


Metabiosis commensalism occurs as one organism creates a suitable environment for the other.

Parasitism

happens when one organism benefits from the process while the other one is hurt or killed. There are two types of parasitism:


Biotrophic parasitism is when the host is harmed but not killed.


Necrotrophic parasitism is when the host is killed.

How humans are impacting the environment

Human are impacting the environment positively by protecting plants and animals with laws. We are also making many parks to help. Humans are also impacting the environment negatively by off-roading. We drive over the gravel and leave trails which is killing the vegetation. If the vegetation is hurt so is the animals. Humans are also killing animals on sight.

Three major organisms

1. The cactus (producer) is providing energy to the primary consumers.


2. The lizard (secondary consumer) is making sure there is not too many primary consumers.


3. The hawk (tertiary consumer) is making sure that there is not too many secondary consumers.
