Explain what an ecosystem is and provide an example of a network of interactions among living organisms and their environment.
Explain what an ecosystem is and provide an example of a network of interactions among living organisms and their environment.
An ecosystem is a community of living organisms (biotic components) interacting with each other and their non-living environment (abiotic components). For example, a forest ecosystem consists of trees, animals, soil, sunlight, and water, all interacting with each other and the physical surroundings.
Identify one biotic and one abiotic component in an ecosystem and describe their interactions.
Identify one biotic and one abiotic component in an ecosystem and describe their interactions.
A biotic component in an ecosystem can be a plant, such as a tree, interacting with an abiotic component like sunlight. The plant uses sunlight for photosynthesis, which is essential for its growth and survival.
Describe the roles and relationships between producers, consumers, and decomposers within an ecosystem.
Describe the roles and relationships between producers, consumers, and decomposers within an ecosystem.
Producers, such as plants, convert energy from the sun into food through photosynthesis. Consumers, including animals, obtain energy by consuming other organisms. Decomposers, like bacteria and fungi, break down dead organic matter and recycle nutrients back into the ecosystem.

Study Notes
Ecosystem Overview
- An ecosystem is a community of living organisms (biotic factors) and non-living components (abiotic factors) interacting with each other in a specific environment.
Components of an Ecosystem
- Biotic Component: Living organisms such as plants, animals, and microorganisms.
- Abiotic Component: Non-living factors such as light, temperature, water, soil, and nutrients.
Interactions within an Ecosystem
- Producers: Autotrophic organisms (e.g., plants, algae) that produce their own food through photosynthesis.
- Consumers: Heterotrophic organisms (e.g., animals) that obtain energy by consuming other organisms.
- Decomposers: Organisms (e.g., bacteria, fungi) that break down dead organic matter, releasing nutrients back into the ecosystem.
- Decomposers play a crucial role in recycling nutrients, maintaining soil quality, and supporting ecosystem health.
Energy Transfer in a Food Chain
- Energy is transferred from one trophic level to the next through consumption of organisms.
- Altering any part of the food chain can have ripple effects throughout the ecosystem, potentially disrupting energy flow and ecosystem balance.
Ecosystem Definitions
- An ecosystem is not just a collection of living organisms, but also includes the physical environment and interactions among all components.
- Biotic components include all living organisms within an ecosystem.
- Abiotic components include all non-living factors that affect the ecosystem.
Decomposers' Role
- Decomposers are essential for ecosystem functioning, as they recycle nutrients, facilitate nutrient cycling, and support ecosystem health.
