An ecosystem is a community of living organisms (plants, animals, and microorganisms) and their physical environment (air, water, and soil) that interact with each other as a unit. It includes both the living and nonliving components of an environment and the relationships between them. The term ecosystem can refer to a variety of scales, from a small pond to a vast rainforest or the entire planet.

In an ecosystem, the various species interact with one another and with their surroundings in a variety of ways. These interactions can be competitive, such as when two species compete for the same limited resources. They can also be cooperative, such as when different species work together to achieve a common goal. The overall health of an ecosystem depends on the balance of these interactions. If one species becomes too numerous or too dominant, it can upset the delicate balance and have negative effects on the other species in the ecosystem. This is why it is important to protect and preserve ecosystems, to ensure that they can continue to support a diverse array of life.

Ecosystems are constantly changing and evolving, and they play a vital role in the health and functioning of the planet. They provide a range of benefits to humans, including food, medicine, clean air, and water, as well as recreational and aesthetic value. 

A biome is a large, distinct region of the Earth that is characterized by a particular climate and a unique set of plants and animals. There are many different biomes on Earth, each with its own unique features and characteristics. Some of the main biomes of the Earth include:

What are the differences between Biome and Ecosystem? 

A biome is a large area characterized by its climate, vegetation, and animal life. Biomes are often defined by the dominant plants and animals that live within them and are adapted to the conditions of that particular environment. Examples of biomes include forests, grasslands, deserts, tundra, and oceans.

An ecosystem is a smaller unit that includes all of the living and nonliving things in a specific area, as well as the interactions between them. Ecosystems can be as small as a puddle or as large as a forest, and they can be found within biomes or other larger areas. An ecosystem includes all the living organisms in an area, as well as the abiotic (nonliving) factors that they interact with, such as water, sunlight, temperature, and soil.

In summary, a biome is a large area characterized by its climate and the plants and animals that live within it, while an ecosystem is a smaller unit that includes all of the living and nonliving things in a specific area, along with the interactions between them.

How to set up a small experimental ecosystem?

Setting up a small ecosystem in a jar/ bottle is, also known as a terrarium. Here are the steps you can follow to create your own terrarium:

To know how to make an closed ecosystem in a jar watch the given video.

Observations to make in an ecosystem

There are many different things that you can observe in a jar ecosystem, depending on the specific species and processes that you include in the jar. Some things that you might observe in a jar ecosystem include:

By carefully observing and documenting these and other processes in a jar ecosystem, you can gain valuable insights into the functioning and dynamics of an ecosystem.
