ecosystem characterized by being sufficiently spaced so that the canopy does not close. Savannas are also characterized by seasonal water availability‚ with the majority of rainfall confined to one season. Savannas are associated with several types of biomes. Savannas are frequently in a traditional zone between forest and desert or grassland. The Savanna covers approximately 20% of the earth’s area. The Savannas is a wet and dry climate‚tropical savanna monthly dry season. Its the driest month of the

Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? In my own opinion No but as u read more about it some things need to be preserved. For instance animals help the crops of the foods that we eat. Snakes help to cure different diseases. Humans help the plants and animals to grow. The fact that human beings are a species means that they depend on many other species

Conservation of Biodiversity One of the most pressing environmental issues today is the conservation of biodiversity. Many factors threaten the world’s biological heritage. The challenge is for nations‚ government agencies‚ organisations and individuals to protect and enhance biological diversity‚ while continuing to meet people’s needs for natural resources. Biodiversity is the existence of a large number of different kinds of animals and plants which make a balanced environment. Biodiversity is the result

‘Define Biodiversity and using examples‚ explain why it is important’ Biodiversity is the variety of life on earth. A fuller definition is given in the Convention on Biological Diversity (CBD) from the 1992 Earth summit: ‘Biodiversity is the variability among living organisms from all sources‚ including terrestrial‚ marine‚ and other aquatic ecosystems and the ecological complexes of which they are part ; this includes diversity within species‚ between species and of ecosystems’ (Hambler‚ C.‚ 2004

Wetlands are home to a diverse community of invertebrates‚ which in turn support a wide variety of birds. Wetlands are among the most productive biomes on Earth. Their water-saturated soils favor the growth of plants such as floating pond lilies and emergent cattails‚ many sedges‚ tamarack‚ and black spruce‚ which have adaptations enabling them to grow in water or in soil that is periodically anaerobic

Why Preserve Biodiversity? ANSWERS 1. Define the term “biodiversity” Biodiversity‚ or biological diversity‚ is the term for the variety of life and the natural processes of which living things are a part. This includes the living organisms and the genetic differences between them and the communities in which they occur. The concept of biodiversity represents the ways that life is organized and interacts on our planet. 2. What is ecology? Ecology is the study of organisms and their relationship with
