the maximum population size of the species that the environment can sustain indefinitely
things that are need for survival
3. smaller fish that wont eat bigger fish
4.sharks eat out fish that need to be gone
In biology, population growth is the increase in the number of individuals in a population. The population growth rate is the rate at which the number of individuals/animals in a population increases in a given time period as a fraction of the initial population
a limiting factor is a factor that limits the reaction rate in any physiological process governed by many variables
10 rabbits may live in a habitat that has enough water, cover and space to support 20 rabbits, but if there is only enough food for ten rabbits, the population will not grow any larger.
also if the animals dont have food how are they going to live. for instance a predator could be a shark or whale and the prey could be a medium sized fish
definition of an organism : a form of life composed of mutually interdependent parts that maintain various vital processes.
producers are important because the plants give energy to the other animals to live and and not die out
consumers:Ecology. an organism, usually an animal, that feeds on plants or other animals.
A carnivore is an animal that gets food from killing and eating other animals.
An omnivore: is an animal that eats food from both plants and animals, which may include eggs, insects, fungi and algae.
A herbivore: is an animal that gets its energy from eating plants, and only plants. Omnivores can also eat parts of plants, but generally only the fruits and vegetables produced by fruit-bearing plants.
Decomposers and scavengers break down dead plants and animals. They also break down the waste (poop) of other organisms. Decomposers are very important for any ecosystem. If they weren't in the ecosystem, the plants would not get essential nutrients, and dead matter and waste would pile up.
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. Scavengers play an important role in the ecosystem by consuming the dead animal and plant material.
food chains and food webs
if you were to remove all of the small little tadpoles in the ocean the other fish would not have any food to eat therefor the fish would die out causing another animal to die because the animal that ate the fish wouldn't have food to eat
trophic levels and energy pyrimids
Traditionally, these diagrams place the primary producers (photosynthetic organisms such as plants) at the bottom and the highest trophic levels at the top of the diagram. The size of the portion of the diagram associated with each trophic level illustrates the amount of energy, biomass, or number of individuals found in each trophic level.producers are at the bottom because that gives the animals energy
