Microorganisms, plants, animals, and ecosystems such as coral reefs, forests, rainforests, and deserts are all  examples of biological diversity . Importance of Biodiversity Biodiversity benefits the Earth in a multitude of ways. The following are some examples: Ecological stability is provided through biodiversity. Within an ecosystem, each species serves a certain purpose. Organisms capture and store energy from the sun (the Earth's sole source of energy), produce organic material and destroy organic stuff. Biodiversity aids the water and nutrient cycle throughout the ecosystem, reduces soil erosion, and aids in the fixation of atmospheric gases so that they can be used by various organisms. Biodiversity regulates the climate. A healthy ecosystem supports the production of products and services that humans require to survive. The

Characteristics of Living Things Class 12

10 Characteristics of Living Things Notes for Class 12 Cellular respiration allows animals to receive the energy that cells require to perform their jobs. Food is absorbed for energy, while waste is removed from the body. Birth, growth, reproduction, and death are the four stages of their life cycle. Living creatures include animals, birds, insects, and people. Converting, growing, reproducing, breathing, and transferring cells, DNA, and nourishment are all abilities that organisms possess. Scientists use these characteristics to distinguish natural elements from inorganic ones. DNA & CELLS Cells are the building blocks of all living things. Cells, which are arranged into groups such as organs, molecules, and other multicellular classifications, can reproduce, express themselves, and respond to particular stimuli, and are thus considered organisms by scientists. METABOLIC ACTIVITY He must ingest food and convert it into energy for his body in order to survive. All living creatures
