Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught

by 1‚360 experts in 95 nations‚ said a rising human population had polluted or over-exploited two thirds of the ecological systems on which life depends‚ ranging from clean air to fresh water‚ in the past 50 years. "At the heart of this assessment is a stark warning‚" said the 45-member board of the Millennium Ecosystem Assessment. "Human activity is putting such strain on the natural functions of Earth that the ability of the planet’s ecosystems to sustain future generations can no longer be

Technology has provided society with different ways of communication‚ but the excessive use of technology is causing a decrease in human interaction and the public’s human intelligence level‚ leaving children today to live a computer-only lifestyle. Scientists are continuing to improve technology at an accelerating rate while providing society with more access to different forms of technology. It

In the rainforest ecosystem‚ everything is connected to one another. There is an interconnectedness existing in this ecosystem. To continue to function‚ the ecosystem depends on the interactions between the biotic and abiotic factors. An ecosystem survives by a combination of energy flow and matter recycling. To understand the interconnectedness of the ecosystem‚ food webs and food chains could be observed. Each organism depends on each other to survive and maintain their populations. In the food

Colonisation and Succession in an Ecosystem 1. Ecosystem is a community of organisms which interact with their non-living environment and function as a unit. 2. Habitat is a natural environment where organisms live. Also provide shelter‚ food‚ living space‚ nesting sites and mates. 3. Species is a group of organisms that look alike and have similar characteristics‚ share the same roles in an ecosystem and are capable of interbreeding to produce fertile offspring. 4. Population is

What Shapes an Ecosystem? Ecosystems are made up of: * Biotic factors- all living parts of an ecosystem (plants‚ animals‚ bacteria) * Abiotic factors- all nonliving (but natural) parts of an ecosystem (soil‚ wind‚ water) These factors together (biotic and abiotic) determine which types of organisms can live in that particular ecosystem. A habitat- the place where an organism lives- includes both biotic and abiotic factors A niche includes both the habitat of an organism and its unique

A food web is the entirety of interrelated food chains in any and every ecosystem. This delicate balance is the connection between predator and prey‚ consumer and producer‚ and autotroph and heterotrophs. Food web’s also allows you to follow the direction of the flow of energy as each organism consumes each of their indicated food sources. For example‚ the energy from the sun is taken in by producers‚ such as ‚ trees‚ grass and fruit. Then goes to an autotroph would be eaten by a second trophic
