Question

Which of these are Abiotic and Biotic?


rain

people

horse


sunlight


dead leaves


wind

Answer 1

Humans can have positive and negative impacts on the environment. For example, ______, which involves removing trees from previously wooded areas to make way for farming or other human activities, can have negative impacts on the environment. Likewise, when human activities result in bodies of water being contaminated with excess fertilizer, this _______ can result in negative impacts like algae overgrowth. Yet another kind of negative impact can come from accidental or intentional introduction of _____, which are organisms that are not native to a particular ecosystem. However, _______, efforts by humans can help to protect and preserve the environment.

Answer 2

In the context of ecology, abiotic factors refer to the non-living components of an ecosystem, while biotic factors refer to the living organisms. Here’s the classification based on your list:

**Abiotic:**
- Rain
- Sunlight
- Wind

**Biotic:**
- People
- Horse
- Dead leaves (while dead leaves originate from living plants, they are often considered biotic components in ecological contexts, particularly in terms of organic matter and its role in ecosystems)

So, "dead leaves" can be seen as both biotic in the context of contributing to the biological component of an ecosystem and abiotic in terms of decomposition processes. However, generally, they are classified as biotic.

Answer 3

Here’s a possible completion of your sentences:

Humans can have positive and negative impacts on the environment. For example, **deforestation**, which involves removing trees from previously wooded areas to make way for farming or other human activities, can have negative impacts on the environment. Likewise, when human activities result in bodies of water being contaminated with excess fertilizer, this **eutrophication** can result in negative impacts like algae overgrowth. Yet another kind of negative impact can come from accidental or intentional introduction of **invasive species**, which are organisms that are not native to a particular ecosystem. However, **conservation efforts**, efforts by humans can help to protect and preserve the environment.
