Study Notes

A food chain primarily shows the sequence of organisms that eat other organisms in an ecosystem, with each level representing a trophic level.

A keystone species plays a unique and crucial role in maintaining the structure and function of an ecosystem, having a disproportionate impact on its environment.

Community dynamics refers to the interactions and relationships between different species within a community, including predator-prey interactions, competition, and symbiosis.

Succession describes the process of change in the species composition of a biological community over time, resulting in a more complex ecosystem.

A food web shows the complex network of feeding relationships among different species in an ecosystem, whereas a food chain only shows a single sequence of organisms.

A characteristic of tropical seasonal forests is their high levels of biodiversity and complex structure, with a distinct dry season.

Temperate (mid-latitude) grasslands occur in regions with moderate temperatures and rainfall, often in areas with fertile soils.

Temperate rainforests are characterized by high rainfall, mild temperatures, and a diverse array of plant and animal species.

A defining feature of Arctic Tundra is the Cold, treeless, and permafrost-dominated landscape, with low biodiversity and short growing seasons.

A distinguishing characteristic of Alpine Tundra is the high-altitude, rocky, and treeless landscape, with limited vegetation and harsh climate conditions.
