Carrying Capacity

def. The maximum, equilibrium number of organisms of a particular species that can be supported indefinitely in a given environment

Resources that affect the carring capacity:water, food ,sunlight ,shelter

The population of one species depends on the resources in that habitat  they live in.

If theres to much of one animal then there wont be enough food for all of the them so they die off the wen they repopulate the cycle begins again.

Limiting Factors

Shark-consumer,carnivore

algae-decomposer,scavenger

fish-consumer,omnivores

A predator is an organism that eats another organism. The prey is the organism which the predator eats. Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.

          

Energy Roles

Herbivores are animals which only eat plant material. This means leaves, flowers, fruits or even wood. Sheep, horses, rabbits and snails are well known examples of herbivores which eat grass and leaves. A parrot, however, which eats fruits and nuts can also be called a herbivore.

Omnivores eat both plants and meat. Chickens are omnivores. They eat seeds, but they can also eat worms. human beings are also omnivores, although some people choose not to eat meat. These people are called vegetarians.

Carnivores eat meat. A carnivore is a predator because it has to find and catch its prey. Some carnivores, such as wolves, hunt in a group called a pack. They move silently and slowly to form a circle around their prey before they attack.

Scavenging is both a carnivorous and a herbivorous feeding behavior in which the scavenger feeds on dead animal and plant material present in its habitat. The eating of carrion from the same species is referred to as cannibalism

Decomposers are organisms that break down dead or decaying organisms, and in doing so, carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development.

An autotroph (or producer) is an organism that makes its own food from light energy or chemical energy without eating. Most green plants, many protists (one-celled organisms like slime molds) and most bacteria are autotrophs. Autotrophs are the base of the food chain. Carnivores are animals that eat meat.

Food Chains vs Food Webs

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. Afood web shows the many different paths plants and animals are connected.

what happens if you remove one animal from a food chain or web?

They would have to find another source of food to it. but it depends where about the organism is on the food chain. if it near the beginning it could wreak the whole food chain up and could kill some animal but if there is another source they would have to adapt to surivie.

Trophic Levels and Energy Pyrmid

An energy pyramid is the graphical representation of the trophic levels (nutritional) by which the incoming solar energy is transferred into an ecosystem. The source of energy for living beings on Earth is the Sun

why are producers at the bottom of the energy pyramid?

The producers are at the bottom of the food chain because they can use sunlight and water to make their own food. There is a large amount of producers too. Producers make their own food by photosynthesis.

Photosynthesis

Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. This process occurs in plants and some algae (Kingdom Protista). Plants need only light energy, CO2, and H2O to make sugar.

Energy Transformation

We can see that carbon dioxide and water are converted into glucose and oxygen with the help of light energy. The masses are not destroyed but are transformed into different form that can be beneficial to other organisms. Cellular respiration is essentially is the "reverse" of the photosynthesis.

tropism

Tropisms are directional movement responses that occur in response to a directional stimulus. Plants are not able to relocated if they happen to start growing where conditions are suboptimal.

Decomposers

Decomposers are organisms that break down dead or decaying organisms, and in doing so, carry out the natural process of decomposition. Like herbivores and predators, decomposers are heterotrophic, meaning that they use organic substrates to get their energy, carbon and nutrients for growth and development.

If all Decomposers wold die there would be no decomposition of waste materials.
Decomposers like backteria and fungi are very beneficial,they recycle materials.
If they would have been much accumlation of dead bodies and life would be impossible.
There would be no organic nutrients and all the dead plants would ruin animals and habitat. The ecosystem would be filled with plants and animal waste
