what are the necessary conditions for the existence of an ecosystem?
235638
An ecosystem must contain producers, consumers, decomposers, and dead and inorganic matter. All ecosystems require energy from an external source – this is usually the sun. Plants need sunlight to photosynthesise and produce glucose, providing an energy source for other organisms.

Biotic and abiotic are the two essential factors responsible for shaping the ecosystem. The biotic factors refer to all the living beings present in an ecosystem, and the abiotic factors refer to all the non-living components like physical conditions (temperature, pH, humidity, salinity, sunlight, etc.)

Depending on the organism, these needs may include: air, water, nutrients, food, light, shelter, space, certain temperatures, etc. Plants need soil, nutrients, sunlight, water, space, air and appropriate temperatures to survive. Animals need food, water, shelter, oxygen, space and appropriate temperatures.

The biodiversity of an ecosystem contributes to the sustainability of that ecosystem. Higher/more biodiversity = more sustainable. Lower/less biodiversity = less sustainable. High biodiversity in an ecosystem means that there is a great variety of genes and species in that ecosystem.

Four (4) conditions for natural selection. Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

If we put populations of different species together, that's called a community. So, a community needs groups of different species to exist. When we add in the abiotic factors, or non-living things in an environment, we get an ecosystem.

Biodiversity and Ecosystem Resilience. Ecosystems involve many complex interactions between members of different species. These interactions often create negative feedback loops, keeping the ecosystem in approximately the same state.

Limiting factors of an ecosystem include disease, severe climate and weather changes, predator-prey relationships, commercial development, environmental pollution and more. An excess or depletion of any one of these limiting factors can degrade and even destroy a habitat.

Biotic factors that a population needs include food availability. Abiotic factors may include space, water, and climate. The carrying capacity of an environment is reached when the number of births equal the number of deaths.

The Components of an Ecosystem There are four basic components of an ecosystem: abiotic substances, producers, consumers, and reducers, which are also known as decomposers. Abiotic means that a substance is devoid of life, it is physical and not derived from living organisms.

An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there.
1223411
Levels of organization in ecology include the population, community, ecosystem, and biosphere. An ecosystem is all the living things in an area interacting with all of the abiotic parts of the environment.

Ecosystem: An ecosystem consists of all the biotic and abiotic factors that influence that community. Ecosystem ecologists often focus on flow of energy and recycling of nutrients.

A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). Healthy ecosystems have an energy source, usually the sun.

Environment refers to the surroundings, whereas, ecosystem is the interaction between the environment and the living organisms. Environment is the area where living organisms live. Ecosystem is the community where the biotic and abiotic elements interact with each other.

One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis, the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis.

Temperature, soil, and the amount of light and water help determine what life exists in a biome. A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there.
