An ecosystem is a community of living organisms (plants‚ animals and microbes) in conjunction with the nonliving components of their environment (things like air‚ water and mineral soil)‚ interacting as a system. These components are regarded as linked together through nutrient cycles and energy flows. As ecosystems are defined by the network of interactions among organisms‚ and between organisms and their environment‚ they can come in any size but usually encompass specific‚ limited spaces (although

time. The evolution of our earth‚ and it species has been a very debated topic over time. There is a lot of evidence that supports evolution and you have found a lot of great evidence that proved this theory to be true. The proposal that species variation locally‚ globally and over time was your idea‚ and is agreed with widely today. Natural selection is one of your other theories that is known all over the world today. Both natural selection and species variation have helped develop the theory

The Impact of Humans on the Biological Diversity of Natural Ecosystems Introduction Since humans have come into existence they have always been a cause of change of whatever natural areas they inhabit along with the living organisms of those natural areas. The different types of organisms such as plants‚ animals‚ and microorganisms that inhabit these areas are known as biological diversity or biodiversity. (USEPA 2010 ) Biological diversity can be affected by many different things‚ climate change

WHAT IS ECOSYSTEM An ecosystem consists of the biological community that occurs in some locale‚ and the physical and chemical factors that make up its non-living or abiotic environment. There are many examples of ecosystems -- a pond‚ a forest‚ an estuary‚ grassland. The study of ecosystems mainly consists of the study of certain processes that link the living‚ or biotic‚ components to the non-living‚ or abiotic‚ components. Energy transformations and ecosystem components are the two main topics

the Origin of Species by Means of Natural Selection was highly controversial and not widely accepted. The ideas Darwin wrote about in his book had never been heard before and went completely against the church. Darwin said that all species on the Earth originated from one common ancestor. Then as time went on‚ that one species adapted differently based on the environment they were in. This kept happening until they became completely different species. He also said that if a species doesn’t adapt
