What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages where different species of plants and animals colonize an area.

Front

What are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession (occurs in lifeless areas) and secondary succession (occurs in areas where a disturbance has destroyed an existing ecosystem).

Front

What is the role of pioneer species in ecological succession?

Back

Pioneer species are the first organisms to colonize a barren environment, initiating the process of ecological succession by creating conditions suitable for other species.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in Earth's atmosphere that trap heat, including carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What percentage of the Earth's atmosphere is made up of greenhouse gases?

Biosphere, Biome, Ecosystem, Community, Population, Individual.

Front

What is a biome?

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What is the difference between a population and a community?

Back

A population is a group of individuals of the same species living in a specific area, while a community is made up of different populations of various species interacting in a particular environment.
