A terrestrial biome characterised by regular, heavy rainfall with the humidity of 80+ percent and biodiversity.

It is the position of an organism occupied in a food chain.

These are the organisms that are very closely associated with another.

A graph showing the number or proportion of individuals surviving at each age for a given species.

Succession that occurs after the original population has been destroyed or disturbed as with forest fire.

Flat grassland with scattered trees in tropical or subtropical regions.

Are those that place an emphasis on a high growth rate and typically exploit less crowded ecological niches and produce many offspring each of which has a relatively low probability of surviving to adulthood.

It is an organism that cannot fix carbon and uses organic carbon for growth. They depend upon autotrophs for food.

When two species interact with each other beneficially, they have no need to interact with each other. They interact purely for the gain that they receive from doing this.

These are organisms in a n ecosystem that produce biomass from inorganic compounds in most cases photosynthetically.
