Dynamic Ecosystems Flashcard

Front

What is a dynamic ecosystem?

Back

A dynamic ecosystem is a community of living organisms interacting with each other and their physical environment, constantly changing due to various factors such as climate, human activity, and species interactions.

What is a limiting factor in an ecosystem?

Back

A limiting factor is a resource or condition that limits the growth, abundance, or distribution of an organism or a population within an ecosystem. Examples include food supply, shelter, and the presence of predators.

Front

What is competition in an ecosystem?

Back

Competition occurs when two or more organisms or species vie for the same resource, such as food, water, or territory, which can limit their growth and survival.

Front

What is the difference between a community and an ecosystem?

Back

A community consists of all the populations of different species living in a specific area, while an ecosystem includes both the living (biotic) and nonliving (abiotic) components of that area.

Front

What happens to a prey population when its predators are removed?

Back

When predators are removed, the prey population may increase significantly due to reduced predation pressure, which can lead to overpopulation and resource depletion.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants and algae, convert sunlight into energy through photosynthesis, forming the base of the food chain and providing energy for consumers.

Front

What is the impact of invasive species on native ecosystems?

Back

Invasive species can disrupt local ecosystems by outcompeting native species for resources, altering habitats, and introducing diseases, often leading to declines in native biodiversity.

Front

What is symbiosis?

Back

Symbiosis is a close and long-term interaction between two different species, which can be beneficial, neutral, or harmful to one or both parties. Types include mutualism, commensalism, and parasitism.

Front

What is carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a particular species that an environment can sustainably support, based on available resources.

What is the significance of biodiversity in ecosystems?

Back

Biodiversity enhances ecosystem resilience, productivity, and stability, allowing ecosystems to better withstand environmental changes and disturbances.
