Front

K-selected species

Back

Species that produce fewer offspring but invest more time and resources in raising them, often leading to a stable population in a stable environment.

Front

Primary succession

Back

The process of ecological succession that occurs in an area where there is no soil, such as after a volcanic eruption or glacier retreat.

Front

Keystone species

Back

A species that has a disproportionately large effect on its environment relative to its abundance, helping to maintain the structure of an ecological community.

Front

Biomes

Back

Large ecosystems characterized by distinctive types of plants and animals, which are maintained under specific climatic conditions.

Front

Polar wind bands

Back

Wind bands that force cold air to sink, influencing climate and weather patterns.

Front

r-selected species

Back

Species that produce many offspring but invest little in their care, often leading to rapid population growth in unstable environments.

Front

Ecological succession

Back

The process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a mature community.

Front

Pioneer species

Back

The first species to colonize previously disrupted or damaged ecosystems, initiating the process of ecological succession.

Front

Indicator species

Back

Species whose presence, absence, or abundance reflects a specific environmental condition, often used to assess the health of an ecosystem.

Front

Invasive species

Back

Non-native species that spread widely in a new habitat, often causing harm to native species and ecosystems.
