Mini Ecosystems Essay Ecology is the scientific study of all the interrelationships between organisms and their environment. An ecosystem is a biological community and all the non-living factors that affect it. Previously‚ in ---- biology class we created our own mini ecosystem terrariums. Lots of changes go on in ecosystems‚ and we got to record them. A terrarium is a self- contained terrestrial ecosystem that includes several species of plant‚ and sometimes animals too. What we had planned

on global warming‚ the fact remains that humans have an impact on the marine ecosystems through waste from chemicals and debris polluting this vast renewable resource. Based upon current scientific evidence‚ emissions of greenhouse gases from human activities are projected to cause significant global climate change during the 21st century. Such climate change will create novel challenges for coastal and marine ecosystems that are already stressed from human development‚ land-use change‚ environmental

Communities and Ecosystems 37.1 Multiple Species Interact in Communities ~Communities are composed of coexisting populations of multiple species ~An ecosystem consists of a biotic community plus its abiotic environment ~Each species in a community has a place where it normally lives and a set of resources necessary for its life activities ~Ecologists describe the diversity of a community by measuring species richness and the relative abundance of each species. * Populations interact in many

An endangered species is a population of organisms‚ which is facing high risk of becoming extinct because it is either few in numbers‚ or threatened by changing environmental or predation parameters. There are a lot of endangered species in the world right now. They are moving towards being extinct slowly. In fact‚ since a species is not declared extinct until years have gone by since it was last spotted. Tigers are among the animals that are endangered in Asia. The tiger is native to Asia

An endangered species is a species that has very few members left and is therefore at risk of extinction . DO WE KNOW WHATS HAPPENNING AROUND US??? Giant Panda Sea otter Perhaps the cutest sea creature in the world‚ the sea otter is also one of the most vulnerable. In a competition with humans for seafood‚ the sea otters stood little chance and they were driven to near-extinction until the 20th century. Fortunately‚ in one of the greatest marine conservation successes‚ the sea

Ecosystems at Risk Ecosystems and their functioning What is an ecosystem? Ecology – the science that examines the interactions between organisms and their living (biotic) and non-living (abiotic) environment. Groups of organisms and their biophysical environment interact and exchange matter and energy. Ecosystem – the dynamic complex of plant‚ animal and micro-organism communities and their non-living environment as a functional unit. Ecosystems are dynamic; constantly changing and adapting

species are endangered ? ENDANGERED SPECIES: has so few individual survivors that the species could soon become extinct overall or most of its natural range. Characteristics of Extinction-Prone Species: -Low reproductive rate -Specialized feeding habits -Feed at high trophic levels -Large size -Limited or specialized nesting or breeding areas -Found in only one place or region -Fixed migratory patterns -Preys on livestock or people -Behavioral patterns Percentage of Endangered Species

Marine Ecosystems are the largest systems on the planet‚ covering over 70 percent of the Earth’s surface and constituting over 99 percent of the living space on the planet (area x depth). These vast ecosystems are composed of many different habitats which extend from the near shore regions to continental shelves and the deep ocean. They are home to millions of species and provide food‚ income‚ protection‚ and many other vital ecosystem services to billions of people around the world. ECOLOGICAL
