Non-living factors in an environment.
Living factors in an environment.
A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring.
The biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.
Place where an organism or a biological population normally lives or occurs.
Fundamental Niche - An organism free of interference from other species which can use the full range of conditions (biotic and abiotic) and resources in which it can survive and reproduce is called its fundamental niche.
Realised Niche - The part of fundamental niche that an organism occupies as a result of limiting factors present in its habitat.
limit the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem.
The combined mass of water found on, above and below the surface of the Earth.
A population is a group of individuals belonging to the same species that live in the same region at the same time. Population density is a measure of the number of organisms that make up a population in a defined area.
A large community of plants and animals that occupies a distinct region. Terrestrial biomes, typically defined by their climate and dominant vegetation, include grassland, tundra, desert, tropical rainforest, and deciduous and coniferous forests.
An ecotone is a transition area between two biomes. It is where two communities meet and integrate.
An ecosystem is a complex set of relationships among the living resources, habitats and residents (biotic and abiotic factors) of an area.
Earth's lithosphere includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth.
Tolerance refers to the niche breadth, or the range of conditions that an organism can withstand. Therefore, more tolerant organisms can withstand a broader range of conditions.
The blanket of gas on the surface of the earth. Made up of 80% nitrogen and 20% oxygen.
This is an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
Commensalism - One organism benefits, while the other neither benefits nor is harmed.
Parasitism - One organism benefits by harming/feeding off of the other.
Mutualism - Both organisms benefit.
richness, which is the total number of different species in a community.
The process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth. It is a change in the genetic composition of a population during successive generations, often resulting in the development of new species.
An adaptation can be defined as a characteristic of an organism that makes it suited to its environment or its particular way of life. It is a structural, physiological (concerned with the body and how a body functions) or behavioural characteristic that enables the organism to survive and reproduce.
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. Founded by the late great Charles Bossman Darwin.
Ecosystem stability is an important corollary of sustainability. Over time, the structure and function of a healthy ecosystem should remain relatively stable, even in the face of disturbance. If a stress or disturbance does alter the ecosystem is should be able to bounce back quickly.
Biotic Potential
Exponential Population Growth
Environment Resistance
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment.
