Biodiversity

Biology

Not quite remember

I easily remember

Biodiversity can be divided into three types

Genetic diversity, species diversity & ecosystem diversity

Genetic diversity

Gene variation of an individual within a population & the gene variation between different populations of the same species.

Species diversity.

Variation & variability of organisms on Earth

Ecosystem diversity

Biotic community & ecological process in the ecosystem on the land, in the sea and other aquatic environments

Phylogeny

Evolutionary history of species or a group of organisms that are genetically linked.

Homologous structure

A structure (body part or body anatomy) that can be observed across multiple organisms that share the same ancestor.

The common ancestor for an angiosperm (flowering plant):

Non-vascular plants like mosses & seedless vascular plants like ferns.

Importance of biodiversity

Source of food, medicines and education & maintains a balance in nature.

In situ conservation

Conservation that maintains species in their natural habitat.

Ex situ conservation

Conservation of a species outside of their natural habitat.
