What is the difference between ecosystem and biodiversity

Our planet as a whole is an ecosystem , but it contains many others: forests, deserts and oceans for instance, which are themselves made up of smaller ecosystems , for example, coral reefs and shallow seas within the oceans. These in turn are made up of many yet smaller ecosystems , such as mangrove swamps, which border on and grade into terrestrial ecosystems.

Change in one ecosystem will impact on the others with which it overlaps and into which it grades. Species diversity refers to the number of different species in a certain area on the land, water and in burrows. Despite this, the number of species present is probably the most common measure of biodiversity used by conservationists; it is measured in different ways, but most include weighting for numbers of individuals as well as numbers of species.

Every individual is dependent on its environment, both the physical rainfall, soil type, temperature, oxygen gradient, light, etc and living other individuals of its own and other species and how these interact. Change in any aspect of these environments will impact on, and may destroy, whole communities. In addition, the richer the diversity of life, the greater the opportunity for medical discoveries, economic development, and adaptive responses to such new challenges as climate change.

The term ecosystem is defined in many ways for example as a community of living organisms combined with their associated physical environment. Ecosystems are the full tapestry of nature that support life and they also provide valuable services. A few types of ecosystems can be mentioned as follows;. Wetland ecosystems filter out toxins, clean the water, and control floods. Then Estuaries ecosystems act as marine-life nurseries. Forest ecosystems supply fresh water, provide oxygen, control erosion, and remove carbon from the atmosphere.

Many species, working together, are needed to provide these critical services. As greater fluctuations occur, ecosystems as a whole become less stable.

Instability causes ecosystems to be more vulnerable to extreme conditions and may also decrease productivity.

Not a day, hour, or even second goes by that we do not depend on biodiversity for survival. The air we breathe is a product of photosynthesis by green plants.

Insects, worms, bacteria and other tiny organisms break down wastes and aid in the decomposition of dead plants and animals to enrich soils. More than 90 percent of the calories consumed by people worldwide are produced from 80 plant species. Almost 30 percent of medicines are developed from plants and animals, and many more are derived from these sources. During Malaria epidemic a medicine called quinine was a plant product.

It was extracted from cinchona tree but when the demand was too high, it was chemically synthesised. Some tonic water and Vodka has this bitter taste due to quinine.

Biodiversity also helps us in our day-to-day lives. Unfortunately, the greenhouse gases produced by human activities are building up in the atmosphere and causing climate change. Climate change is a major threat to biodiversity. The people are aware that the climate change is due to contribution of carbon dioxide in the atmosphere and some of it is responsible due to human activities.

Let me ask you, would you agree that some carbon dioxide is added by burning methane? The answer is yes, methane we use for cooking.

This component of biodiversity is important because it allows populations to adapt to environmental changes through the survival and reproduction of individuals within a population that have particular genetic characteristics that enable them to withstand these changes.

The maintenance of high genetic diversity within populations is therefore a conservation and management priority as this provides the greatest capacity for any population to adapt to a broad range of environmental changes. Conversely, failure to maintain genetic diversity limits the capacity for a population to adapt, making it vulnerable to even small changes in the environment and increasing the likelihood of extinction.

Species Diversity is simply the number and relative abundance of species found in a given biological organisation population, ecosystem, Earth.

Species are the basic units of biological classification and hence, this is the measure most commonly associated with the term 'biodiversity'. Worldwide, about 1. However, many environments and groups of organisms are not well studied and estimates of species numbers range from 3 to million.

Diversity in species is important for economic, biological, social and cultural reasons.
