Habitat: the environment in which a species normally lives, or the location of a living organism. Population: a group of organisms of the same species who live in the same area at the same time. Community: a group of populations living and interacting with each other in the same geographica...
5.1.1 Define species, habitat, population, community, ecosystem and ecology. Species: a group of organisms that can interbreed and produce fertile offspring. Habitat: the environment in which a species normally lives or the location of a living organism. Population: a group of organisms of the ...
Ecology at the level of individuals is concerned chiefly with the individual organism’s physiology, reproduction, and development. At the level of population, ecology deals primarily with the attributes and the various factors affecting the population. At the level of community, ecology studies the ...
Biome, the largest geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions. It includes various communities and is named for the dominant type of vegetation, such as grassland or coniferous for
The exploitation of the natural resources to the point of diminishing returns has significantly destroys the ecosystem. Activities such as over hunting, over fishing, over mining, and excessive logging have led to a reduction in community structures, population distributions, and species breeding. For...
(Suding et al., 2004;Hobbs et al., 2013). Here, we consider the effects of both natural disturbance and anthropogenic stressors on receptor organisms and processes that occur at the population, community, and ecosystem levels. At the population level, anthropogenic and natural stressors act on...

body size and growth rates are clearly traits that can both influence the capacity of an organism torespondto the environment (with stress often favouring small-sized, fast growing taxa), and also theireffectson processing of resources and community-level productivity (Fig. 2). Identifying the sp...
If the ecosystem is described in hierarchical terms (e.g. genome and phenome, organism, population, community), the adaptability can be split into components associated with gene pool diversity; physiological, behavioral, and developmental plasticity; culturability; social plasticity; and reroutability ...
Body mass is a fundamental organism trait that affects metabolic rate, energy demand and uptake rate9,14,15, and is an important characteristic of overall population and community structure through density-mass allometric relationships14. Even though high numbers of small individuals may dominate ...
