Answer:
The living components of an ecosystem (everything that's alive) are called biotic factors.An ecosystem is a community of organisms and non-living components that interact as a system. The "system" part of the word ecosystem is what's most important. It means that everything interacts either directly or indirectly. Energy and nutrients are cycled throughout all the different components of the ecosystem. We can show the way energy flows using food chains or food webs.
The living components of an ecosystem (everything that's alive) are called biotic factors. The non-living components like heat and nutrients are called abiotic factors. Both biotic and abiotic factors contribute to an environment's health. Biotic factors include plant productivity and animal behavior. Abiotic factors include the climate and amount of sunlight.

Effects of Human Activity
Like any other living thing, we influence our environment. So what do uniquely human activities like industry do to ecosystems? Historically, we haven't treated our biosphere so well. That's a big part of why climate change is happening so rapidly.
One example is that waste, like chemicals from factories or everyday garbage, used to be dumped into waterways. Organic matter and energy cycle through every trophic level in an ecosystem. So, changes caused by this dumping—like shifts in pH or available nutrients—affected a whole host of organisms. Ironically, this dumping also affected human health.
Today, scientists know a lot more about the balance of nature. That's why we have so many more resources now to help our environment. Some examples include sustainable food production and sustainable waste management. The benefits we receive back from the environment (such as food and drinking water) are known as ecosystem services.
Explanation:
Answer:
An ecosystem consists of all the organisms and the physical environment with which they interact. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. In other words, a community is the biotic, or living, component of an ecosystem. In addition to this biotic component, the ecosystem also includes an abiotic component, the physical environment.
