Short note on ecosystem services

plz answer it related to ncert syllabus

Ecosystems are communities formed by the interaction between living (plants, animals, microbes) and non-living organisms (air, water, mineral soil).

Human beings are both part of ecosystems and benefit from ecosystems in many ways. The benefits are known as ECOSYSTEM SERVICES.

Acoording to NCERT:

Healthy ecosystems are the base for a wide range of economic,

environmental and aesthetic goods and services. The products of

ecosystem processes are named as ecosystem services, for example,

healthy forest ecosystems purify air and water, mitigate droughts and

floods, cycle nutrients, generate fertile soils, provide wildlife habitat,

maintain biodiversity, pollinate crops, provide storage site for carbon

and also provide aesthetic, cultural and spiritual values. Though value

of such services of biodiversity is difficult to determine, it seems

reasonable to think that biodiversity should carry a hefty price tag.

Robert Constanza and his colleagues have very recently tried to

put price tags on nature’s life-support services. Researchers have put

an average price tag of US $ 33 trillion a year on these fundamental

ecosystems services, which are largely taken for granted because they

are free. This is nearly twice the value of the global gross national

product GNP which is (US $ 18 trillion).

Out of the total cost of various ecosystem services, the soil

formation accounts for about 50 per cent, and contributions of other

services like recreation and nutrient cycling, are less than 10 per

cent each. The cost of climate regulation and habitat for wildlife are

about 6 per cent each.

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.........

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. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts.

An ecosystem is a large community of living organisms (plants, animals and microbes) in a particular area.[2] The living and physical components are linked together through nutrient cycles and energy flows.[3] Ecosystems are of any size, but usually they are in particular places.

Each ecosystem has its own community. An aquarium community, for example, can have small fish and other organisms. A desert community may have cacti, small snakes, and scorpions. A pond community can have frogs, insects, snakes, and plants, and a forest community may have rabbits, foxes and pine trees. The species in a community are divided into populations according to the particular habitats and ecological niches in the ecosystem.
