What are the main components of an ecosystem?

• The main components of an ecosystem are biotic and abiotic factors.

• Sunlight and temperature alone

• Water and soil only

• Only plants and animals

Define biotic components in an ecosystem.

• Abiotic components are the non-living elements in an ecosystem.

• Biotic components include only plants and animals.

• Biotic components refer to the physical environment of an ecosystem.

• Biotic components are the living organisms in an ecosystem.

What role do abiotic factors play in an ecosystem?

• Abiotic factors are only harmful to ecosystems.

• Abiotic factors have no impact on living organisms.

• Abiotic factors are solely responsible for the evolution of species.

• Abiotic factors are essential for shaping ecosystems by influencing climate, habitat conditions, and resource availability.

Give examples of producers in an ecosystem.

• Decomposers like fungi

• Carnivores such as lions

• Herbivores like rabbits

• Examples of producers include plants, algae, and cyanobacteria.

What are consumers and how do they function in an ecosystem?

• Consumers are organisms that do not interact with other species in their environment.

• Consumers are organisms that decompose dead matter and recycle nutrients.

• Consumers are only plants that produce energy through photosynthesis.

• Consumers are organisms that obtain energy by consuming other organisms and function as key players in energy transfer within ecosystems.

Explain the significance of decomposers in an ecosystem.

• Decomposers compete with producers for resources.

• Decomposers primarily produce energy for the ecosystem.

• Decomposers are crucial for nutrient cycling and maintaining ecosystem balance.

• Decomposers are only important in aquatic environments.

How do energy flows through an ecosystem?

• Energy flows from the sun to producers, then to consumers, decreasing at each trophic level.

• Energy flows in a circular pattern without loss at each level.

• Energy flows from consumers to producers, then to the sun.

• Energy is recycled within the same trophic level only.

What is the difference between a food chain and a food web?

• A food chain is linear, while a food web is a complex network of interconnected food chains.

• A food web is always shorter than a food chain.

• A food chain is more diverse than a food web.

• A food chain includes multiple species, while a food web includes only one species.

Describe the concept of ecological niches.

• An ecological niche refers to the physical appearance of an organism.

• An ecological niche is a type of plant species.

• An ecological niche is the geographical location of a species.

• An ecological niche is the role and position of a species in its environment, including its habitat, resource use, and interactions with other organisms.

How do human activities impact ecosystem components?

• Human activities negatively impact ecosystem components by causing habitat loss, pollution, and biodiversity decline.

• Human activities enhance ecosystem components by increasing biodiversity.

• Human activities have no effect on ecosystem components.

• Human activities only benefit ecosystem components through conservation efforts.
