Causes and Impacts of Genetic Erosion
In the modern age of industrialization and competition for development, the human race has badly missed its traditions up to major extents and cultures- up to some extent.

Disruption of Food-chains and Genetic Erosion
The population explosions of earlier and present days have already caused and are still causing serious impacts on the global environment. As for the biological environment, the human population has stressed most biological systems, comprising flora and fauna, as well as biological diversity.
Positive and Negative Interdependence among Organisms in Ecosystems
Interdependence between two species through which individuals of either one or both species benefit is called positive interdependence. The benefits to the individual of any species through this relationship may be continuous or transitory, obligate or facultative. Both partners in this type of relationship may be in close contact; one may be inside some specific area or attached to the surface of the other’s body. Positive interdependence is divided into three major types: mutualism, Commensalism, and proto-cooperation.
Macro and Micro Ecosystems and Relation among Organisms
A habitat is the natural home or environment of an animal, plant, or other organism.
Types of Ecosystems – Terrestrial and Aquatic
Ecosystems can be categorised into two broad categories: natural and artificial. Natural Ecosystems are those ecosystems that operate by themselves under natural conditions. These ecosystems are further categorized as Terrestrial and Aquatic Ecosystems. Terrestrial ecosystems relate to lands, whereas Aquatic ecosystems relate to fresh or marine water. Freshwater ecosystems may be Lotic or Lentic. Lotic are running water ecosystems like springs, streams or rivers, whereas Lentic Fresh Water Ecosystems may be found in standing waters of lakes, ponds, pools, puddles, ditches, swamps, etc. Marine Ecosystems are found in marine waters of salt lakes, seas, oceans and estuaries. Artificial Ecosystems are man-engineered ecosystems like crop fields, artificial ponds and lakes, aquaria, fish ponds, and abandoned mines reclaimed as lakes or water bodies for recreation.
Structure and Functions of Ecosystems
The environment has two basic components: Biotic and Abiotic. The biotic components of an ecosystem are living beings—plants, animals, and…
Adaptations to Environmental Changes
The conditions of a habitat remain changing abruptly and periodically. Abrupt changes in environment often do not give time to an organism to get ready and to face the challenges. As such the organism can survive only when it has sufficient abilities to tolerate these changes.
What is the interaction between members of the same species?
Living beings interact with each other, with members of other species, and with components of the abiotic environment in an…
What is an Ecological Niche? How is it related to habitat?
Ecological Niche Dictionary defines the term Niche as a comfortable or suitable position in the life of a living being or a role taken by a type of organism within its community. In other words, an ecological niche is the role and position a species has in its environment, for example, how it meets its food and shelter needs, survives, and reproduces. A species’ niche includes all of its interactions with its environment’s biotic and abiotic factors.
What is Ecosystem? What are its components?
The environment of our earth has a number of life zones that support birth and development of all types of organisms.
All the life zones of the earth are collectively called as Biosphere.
The biosphere vertically extends into the atmosphere up to about 10 km and downwards into the oceans up to a depth of about6.9 km.
