Atmosphere is essential for life on Earth as it supplies oxygen, water, CO2 and some nutrients (N) to living organisms, and protects living organisms from temperature extremes and excessive UV radiation.
In addition to being important for life, the atmosphere also allows the harvesting of a number of primary energy sources. For example, the oxygen in the atmosphere makes combustion of hydrocarbons (like those found in fossil fuels or biofuels) possible.
The solid particles play an important role in the atmosphere because they act as nuclei for the condensation of water vapour around them.
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
The major types of ecosystems are forests, grasslands, deserts, tundra, freshwater and marine. The word “biome” may also be used to describe terrestrial ecosystems which extend across a large geographic area, such as tundra.
Examples of ecosystems are: agroecosystem, aquatic ecosystem, coral reef, desert, forest, human ecosystem, littoral zone, marine ecosystem, prairie, rainforest, savanna, steppe, taiga, tundra, urban ecosystem and others. plants, animals, soil organisms and climatic conditions.
Ecological Goods & Services. Ecological Goods & Services are the benefits that humans get from ecosystems such as clean water and air. … Examples of ecological services produced from ecosystems are climate regulation, storing carbon, pollination , beautiful viewscapes, and great places for recreation.
Pollination. Insects and wind pollinate plants and trees which is essential for the development of fruits, vegetables and seeds. Animal pollination is an ecosystem service mainly provided by insects but also by some birds and bats. … Important freshwater plants, such as water lilies need pollinators to reproduce.
They provide vital goods and services -particularly freshwater – to a significant proportion of humanity. Mountains are key centers of biological and cultural diversity as well important sites of traditional ecological knowledge, and influence the climate at many scales.
Freshwater ecosystems provide major ecosystem and economic services, and they are irreplaceable reservoirs of biodiversity. Climate moderation, nutrient cycling, waste treatment, flood control, groundwater recharge, habitats for many species, genetic resources and biodiversity, scientific information.
Ecosystem Services. Services provided by the natural world that benefit people. Four Ecosystem services. Supporting, provisioning, regulating & cultural. Supporting services.
Supporting services are: Ecosystem services that are necessary for the production of all other ecosystem services. Some examples include biomass production, production of atmospheric oxygen, soil formation and retention, nutrient cycling, water cycling, and provisioning of habitat.
Biodiversity provides us with drinking water, oxygen to breathe, food, medicine, decomposition of waste, and helps our planet withstand natural disasters.
