Desert Food Chain:
The food chain shows the flow of energy between different organisms in an ecosystem. The plant is fed upon by a herbivore (plant eater) such as the ant. The ant recieves its energy from the plant. The ant is then fed upon by an omnivore (plant and meat eater) such as the lizard. The lizard recieves its energy from the ant whose energy came from the plant. The lizard is then fed upon by a carnivore (meat eater) such as the hawk. The hawk recieves it's energy from the lizard which recieved it's energy from the ant which recieved it's energy from the plant.
Desert Food Web:
A Foodweb is a network or food chains or feeding relationships by which energy and nutrients are passed on from one species of living organisms to another.
Energy Pyramid:
An energy Pyramid shows the amount of energy available in each trophic level of an ecosystem. It shows how the energy level decreases as you move into each trophic level. If there is 100% energy at the first trophic level, then there will be 10% energy at the second trophic level, 1% energy at the third trophic level, and .1% energy at the third, highest trophic level. All of the trophic levels lose energy as heat through cellular respiration. |  |
There are many factors that can limit population growth in the desert. There are density dependent factors and density independent factors.
Density-Dependent Factors Density dependent factors are factors whose effects on the size or growth of the population vary with the population density. There are many types of density dependent limiting factors, they include: 1. Availability of food 2. Parasitism 3. Predation 4. Migration 5. Disease | Density Independent Factors Density independent factors are factors that affects population size independent of the population density. There are many types of density independent limiting factors, they include: 1. Natural Disasters 2. Weather Conditions 3. Soil Quality |
