present in a species or a population‚ the gene pool. Domestication and plant breeding lead to a loss of genetic variety‚ hence the importance of “gene banks” Habitat diversity: The number of different habitats per unit area that a particular ecosystem or biome contains. It is associated with the variety of niches that may be exploited by different species. Conservation of habitat diversity usually leads to the conservation of species and genetic diversity Fitness: The ability for an individual to

create effects that disseminate throughout an entire ecosystem. These interactions‚ or lack thereof‚ specifically result in trophic cascades. Cascading trophic effects typically occur from a change in the population density of apex predators. Due to the ever increasing impact of humans on nature‚ this field of ecological study is gaining more popularity as ecologists desperately try to understand the various influences of apex predators on ecosystem functioning. Numerous studies have displayed diverse

Hardwood evergreen trees which are widely spaced and are found in the Mediterranean region are olive‚ cork‚ oak and stone pine. Temperate Forests The temperate forest biome is found in regions where winters are cold and summers are warm. Regions with this climate are common in the mid-latitudes‚ far from both the equator and the poles. Tropical rainforests are in regions that are consistently warm all year long‚ close

factors are the primary determinants of species composition in a community‚ and organisms are largely interdependent on each other. According to organismic concept it is expected that an entire community or biome will respond as a unit and to relocate as climatic conditions change. Pleistocene biome migration in response to multiple glaciations‚ the accordian effect‚ is a classic example of this model (Wright‚ 1984). In contrast‚ Wright (1984) further explained that the individualist expects each species

All economic activities affect the environment in some way whether it is done intentionally or unintentionally. These could be positive or negative effects. Most of the time‚ they are negative. Most activities usually end up harming ecosystems or just polluting the environment. Economic activities can range from mining all the way to farming. This essay will discuss different types of economic activities and how they effect the environment. The first effect on the environment is the over harvesting

Q. 1. Explain with diagram the structure and function of environment? Ans. Environment is a collective term for all the conditions in which an organism lives. It includes biotic and abiotic components whereas habitat is a place where an organism lives. The different components of environment are inter-linked and interdependent.
