    Ecosystem can be natural or man-made, large or small, permanent or temporary, complete or incomplete. Natural ecosystem. It is an ecosystem developed under natural conditions without any appreciable human interference. Natural ecosystem can be terrestrial (e.g., forest, desert, grassland) or aquatic (e.g., fresh water, lake, pond, river, sea). Oceans constitute the most stable ecosystem.

    Biomes are climatically and geographically defined as similar climatic conditions on the Earth, such as communities of plants, animals, and soil organisms, and are often referred to as ecosystems. Some parts of the earth have more or less the same kind of abiotic and biotic factors spread over a large area, creating a typical ecosystem over that area. Such major ecosystems are termed as biomes. Biomes are defined by factors such as plant structures (such as trees, shrubs, and grasses), leaf types (such as broadleaf and needleleaf), plant spacing (forest, woodland, savanna), and climate. Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments. Each biome consists of many ecosystems whose communities have adapted to the small differences in climate and the environment inside the biome.

  1. Which one of the following is an abiotic and renewable resource?

    In ecology and biology, abiotic components (also known as abiotic factors) are non-living chemical and physical factors in the environment, which affect ecosystems. Abiotic phenomena underlie all of biology. From the viewpoint of biology, abiotic factors can be classified as light or more generally radiation, temperature, water, the chemical surrounding composed of the terrestrial atmospheric gases, as well as soil. The macroscopic climate often influences each of the above. A renewable resource is a natural resource with the ability to reproduce through biological or natural processes and replenished with the passage of time. Renewable resources are part of our natural environment and form our eco-system.
