Elephants are the gardeners of our forests. An elephant eats abundant amounts of fruit. Some seeds may be defecated intact in a different area located at a distance. From this excreta, a new plant may sprout if conditions are right. In this way the elephants help in seed dispersal in faraway places. Elephants being an […]

Functions of Biodiversity

Humans cannot exist without biodiversity as we use it directly and indirectly in a number of ways. Direct use includes things like food, fibres, medicines and biological control, whilst indirect uses includes ecosystem services such as atmospheric regulation, nutrient cycling and pollination. There are also non-use values of biodiversity, such as option value (for future […]

Biomass Productivity

The rate of generation of biomass in an ecosystem is called Productivity, which is expressed in units of mass per unit surface (or volume) per unit time. Productivity of autotrophs such as plants is called primary productivity, while that of heterotrophs such as animals is called secondary productivity. Primary production is the synthesis of new […]

Niche, Food Chains and Foodweb

Each organism has its own niche—its position or function in a community. Because every species occupies a niche, it’s going to have an effect on all the other organisms. These connections are shown in the food chain. A food chain describes the way different organisms depend on one another for food. There are basically four […]
