carrying capacity

In ecological terms, this environmental resistance produces the carrying capacity of an environment. The carrying capacity is the size of the population or community that can be supported by the surrounding environment. In determining the carrying capacity of any environment, biologists identify limiting factors to population growth. These either promote or hinder growth and can be divided into abiotic or biotic factors.

Abiotic factors are nonliving aspects of the environment that affect the ability oforganisms to survive and reproduce. These often refer to the chemical or physical factors in an ecosystem as seen in the list below.

food, water, shelter, and space

Limiting Factors and Predator/Prey Relationships

As predator population decreases, prey population increases because there are less predators hunting them and they are consequently able to survive. This cyclic pattern continues unless disrupted by a density independent change.

1.Hawk (predator)/lizard (prey).

2.Scorpions (predator)/ insects (prey).

Energy Roles

the producers – that capture the energy  from the sun through the process called “photosynthesis.” Plants use the sun’s energy, with water and carbon dioxide, to produce glucose, a basic component of the food chain.a limithing factor is no water

herbivores -an animal that feeds on plants.

omnivores-an animal or person that eats food of both plant and animal origin

carnivores-an animal that feeds on flesh

decomposers-an organism, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material.

scavenger-an animal that feeds on carrion, dead plant material, or refuse.

Producers ExplanationsThe producers get their energy from the sun. The consumers get their energy from the producers and other animals. Decomposers get their energy consumers. food chains and food webs

A food chain is a single line of organisms, where each is preceded by something that it consumes and is followed by something that consumes it. A food web branches out in all directions with arrows pointing from organisms to any number of organisms that consume it.

if tertiary die the secondary would  in up died then the primary then the population would be died

tropic levels and energy

The higher the triangle get it get smaller because the energy is becoming less.

the producers are on the bottom because they are the first thing  in the food source
