Fall Semester Final Review

Front

What is a food web?

Back

A food web is a complex network of feeding relationships among various organisms in an ecosystem, showing how energy and nutrients flow through different trophic levels.

Front

What is the role of a predator in an ecosystem?

Back

A predator is an organism that hunts and consumes other organisms (prey) for food, helping to regulate population sizes and maintain balance in the ecosystem.

Front

Define invasive species.

Back

Invasive species are non-native organisms that spread widely in a new habitat, often outcompeting native species for resources and disrupting local ecosystems.

Front

What is a biome?

Back

A biome is a large geographical area characterized by specific climate conditions, plants, and animals, such as deserts, forests, and grasslands.

Front

What is a producer in an ecosystem?

Back

A producer is an organism, typically a plant or algae, that can make its own food through photosynthesis, forming the base of the food chain.

Front

Explain the predator/prey relationship.

Back

The predator/prey relationship is an interaction where one organism (the predator) hunts and eats another organism (the prey), influencing population dynamics.

Front

What is mutualism?

Back

Mutualism is a symbiotic relationship between two different species where both benefit from the interaction, such as bees pollinating flowers.

Front

What is competition in ecology?

Back

Competition occurs when two or more organisms vie for the same resources (like food, space, or mates) in an ecosystem, which can limit population growth.

Front

What are the characteristics of a desert biome?

Back

Desert biomes are characterized by low precipitation, extreme temperatures, and sparse vegetation, adapted to conserve water.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity refers to the variety of life in an ecosystem, which contributes to resilience, stability, and the ability to adapt to changes.
