which statement describes a biotic factor interacting with the environment?
The correct answer and explanation is:
Correct Answer:
A biotic factor interacting with the environment refers to any living component that affects or interacts with other organisms or their environment. For example, a bird building a nest in a tree is a biotic factor interacting with its environment.
Explanation:
In ecology, factors that influence ecosystems are divided into two categories: biotic and abiotic factors.
- Biotic factors are the living parts of an ecosystem. These include plants, animals, fungi, bacteria, and any other living organisms. Biotic factors interact with one another and with the physical environment.
- Abiotic factors are the non-living parts of an ecosystem such as sunlight, temperature, water, soil, and climate.
When we talk about a biotic factor interacting with the environment, it means how living organisms influence and respond to their surroundings and other organisms. For example, when a bird builds a nest in a tree, the bird (a living organism) is using the tree (part of the environment) to create shelter. This is a direct interaction between a biotic factor (bird) and the environment.
Other examples of biotic interactions include:
- Plants competing for sunlight or nutrients in the soil.
- Predators hunting prey.
- Fungi decomposing dead organic material.
- Bees pollinating flowers.
These interactions are critical because they shape ecosystems, affect population dynamics, and contribute to the flow of energy and nutrients. The presence and behavior of biotic factors can influence the health and stability of ecosystems. For example, a decline in pollinator populations can affect plant reproduction, which in turn impacts food sources for other animals.
In summary, a biotic factor interacting with the environment is any living organism engaging with either other living things or non-living elements of its habitat, influencing the ecosystem’s structure and function.
