________________________ means the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of ecosystems.

The natural or anthropogenic process that converts forest land to non-forest is called__________________________.

The increase in additions of nutrients to freshwater or marine systems, which leads to increases in plant and algae growth (biological production) and often to undesirable changes in ecosystem structure and function.

The place or type of site where an organism or population naturally occurs.

Any species that is likely to become extinct within the foreseeable future throughout all or part of its range and whose survival is unlikely if the factors causing numerical decline or habitat degradation continue to operate.
