Which of these is a community? O all of the organisms living in your garden O all of abiotic factors that determine the health of your garden o all of the garden snails living in your garden o all of the organisms living in your garden as well as the soil and rocks Question 33 2 pts Our bodies are ecosystems comprising of numerous species that interact with each other and various abiotic factors. O True O False
The Correct Answer and Explanation is :
The correct answer to the first question is:
All of the organisms living in your garden.
A community is defined as all the living organisms in a specific area, interacting with each other. In the case of a garden, the community would include all the plants, animals, insects, and microorganisms that live in that garden and interact with each other. This does not include abiotic factors (like soil, water, or temperature), which are part of the ecosystem but not the community itself.
Here’s why the other options are incorrect:
- All of the abiotic factors that determine the health of your garden: This refers to the non-living factors (e.g., temperature, light, soil type, and water) in the environment. While important for sustaining life, abiotic factors are not considered part of the community.
- All of the garden snails living in your garden: This would be a population of a specific species, not a community. A community consists of many species, not just one.
- All of the organisms living in your garden as well as the soil and rocks: This option refers to the entire ecosystem, not just the community. An ecosystem includes both the living organisms (the community) and the non-living components (like soil, rocks, and water).
For the second question, the correct answer is:
True.
Our bodies are indeed ecosystems. An ecosystem is a biological community of interacting organisms and their physical environment. The human body can be viewed in a similar way, as it hosts numerous species of microorganisms (bacteria, fungi, etc.) that interact with each other and the body’s cells. These microorganisms can affect our health, digestion, immunity, and many other processes. The body’s cells and the microbes interact with various abiotic factors, such as nutrients and oxygen, to maintain balance and function. Just like ecosystems in nature, the human body’s internal environment is highly dynamic, with many systems working together to maintain homeostasis.
In conclusion, both the garden’s organisms and our bodies reflect the concept of ecosystems, where living organisms interact with each other and their environment, but the distinction is made between communities (which only include the living organisms) and ecosystems (which also include non-living components).
