Food Chains and Trophic Levels Quiz

Ecosystems

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

Keystone Species

• 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

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

Succession

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

Food Webs

• 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.

Biomes

Tropical Seasonal Forests

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

Temperate Grasslands

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

Temperate Rainforests

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

Arctic Tundra

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

Alpine Tundra

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