my dear friends ...today I Nikita am going to speak about how human activities are affecting flora and fauna? We are facing a serious crisis in biodiversity‚ the variety of animals‚ plants and their habitats. We humans are part of this biological diversity and depend on it in many ways. The rate that animal and plant species are becoming extinct‚ and the pace at which ecosystems are being destroyed‚ are increasing every day. But we the people‚ particularly of this developed world‚ have become so

Insects are often seen merely as pests or uninvited guests to humanactivities. A large number of insects coexist with us humans and are either harmless or beneficial to our society and its endeavors. Often what is needed is a proper balance between our society and the societies that insect speciesrepresent. The emergence in the mid-20th century of integrated pest management is one aspect of our efforts to live together more successfully. The changes humans have brought upon their ecosystems by monocultures

Chlorine in Photosynthesis Experiment Abstract Photosynthesis the means by which green plants and different types of organisms use light from the sun to synthesize foods from CO2 and H2O. Chlorine is a chemical element usually in the form of a yellow-green gas and is a strong oxidizing agent. Elodea is a type of aquatic plant also known as waterweed that is native to North America. In the experiment that took place‚ the effect of chlorine in the presence of photosynthesis reactions were studied

our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new ecosystems is caused by a number of reasons. In terms of money to be made‚ illegal wildlife smuggling is second to illegal drugs‚ with illegal arms trade right behind. The U.S. State Department reports that this industry is worth around ten billion dollars a year. Plants and animals are commonly imported into this country for luxury

a biological environment consisting of all the organisms living in a particular area‚ as well as all the nonliving or abiotic‚ physical components of the environment with which the organisms interact‚ such as air‚ soil‚ water and sunlight. In a typical ecosystem‚ plants and other photosynthetic organisms are the producers that provide the food. (Leibold) Ecosystems can be permanent or temporary and they usually form a number of food webs. Examples of ecosystem include: Marine Ecosystems: oceans‚ coral reefs‚ intertidal

as small as a tree or a puddle. If you have a terrarium‚ that is an artificial ecosystem. The water‚ water temperature‚ plants‚ animals‚ air‚ light and soil all work together. If there isn’t enough light or water or if the soil doesn’t have the right nutrients‚ the plants will die. If the plants die‚ animals that depend on them will die. If the animals that depend on the plants die‚ any animal that depends on those animals will die. Ecosystems in nature work the same way. All the parts work together
