Answer 1

Everything is interlinked in this natural world. There are a number of different living species, including producers, consumers and decomposers, which associate with each other.

Complete Answer:
A community of living and nonliving things that function together is an ecosystem. Soil, atmosphere, heat and light from the sun, water and living organisms form an ecosystem. There is a lot of species diversity in a stable world and it is less likely to be significantly affected by human interaction, natural disasters and climate change.

Ecosystems don't have a specific scale. They all work together with water, trees, livestock, climate, light and dirt. The plants will die if there isn't enough light or water or if the soil doesn't have the right nutrients. Animals who rely on them will die if the plants die. Any animals that depend on those animals will die if the animals that depend on the plants die.

For example, in the lake ecosystem, the sun enters the water and makes the algae rise. Algae contain oxygen for organisms such as fish and provide calories for animals that are microscopic. The microscopic animals consume small fish, ingest with their gills oxygen, and remove carbon dioxide, which plants then use to expand. Anything else would be affected if the algae died. Microscopic creatures wouldn't have enough calories, fish wouldn't have enough oxygen and some of the carbon dioxides they use to thrive would be wasted by plants.

Hence the correct answer is option A.

Note: The green plants are the producers. They are making food of their own. Consumers are animals and the producers or species who consume producers receive their nutrition. Decomposers are plants and animals that break down into organic products and go back into the soil from dying plants and animals.
