-ABIOTIC COMPONENT, consists of nonliving chemical and physical factors, such as temperatures, light , water , minerals and air. --Biotic Component includes the living factor all the other organisms that are part of an individuals environment. -other organisms compete for food and other resources with individuals. - The specific role or way of life of a species within its environment is its niche. -niche includes -range of conditions that the species can tolerate -the resources it uses -the method by which it obtains resources -the number of offspring it has -the time it reproduces -all other interactions with in its environment.t.
Generalist have a broad niche. they can tolerate a range of conditions and use a variety of resources. EXAMPLE are Virginia possum which eat anything. Specialist have narrow niche they can NOT tolerate a wide range of conditions EXAMPLE koala of Australia which only feed on leaves of eucalyptus trees. Some species have more than one niche in a lifetime. EX caterpillar=eat leaves, Butterflies= feed on nectar.
NICHE- the sum total of an organism adaptations that allows it to exploit resources to meet its needs in its habitat while interacting with the other organisms present accordingly to its activity pattern. The exact habitat of an organism is determined by its ranges of tolerance of physical condition. Because resources like water and food may be limited, plant and animal species often compete with each other for food and water. The only way that they can all live together is if they occupy slightly different niches or hold different "jobs" in the community. No two species can occupy exactly the same niche. They all have their own jobs or niche in the community. A niche is the smallest unit of a habitat that is occupied by a plant or animal. The habitat niche is the physical space occupied by the plant or animal. The ecological niche is the role the plant or animal plays in the community found in the habitat.
NICHE
The diagram represents a tree containing three different species of warbler, A, B, and C. Each species occupies a different niche. A fourth species, D, which has the same environmental requirements as species B, enters the tree at point X. Members of species B will most likely (1.) live in harmony with species D (2.) move to a different level and live with species A or species C (3.) stay at that level but change their diet (4.) compete with species D
