different population densities on the survivorship and reproduction of Daphnia are observed over a two-week period within a lab environment. Over the two week period‚ the numbers of parent Daphnia alive and dead are recorded daily‚ along with the amount of offspring produced each day. From the main parameter investigated‚ the net reproductive rate‚ the results of the experiment support that higher densities result in less successful reproduction and decreased fecundity. Values for the instantaneous

Are Endangered Animals an Issue? There are around 41‚000 endangered species‚ and around 16‚000 of them are on the edge of extinction. There are many reasons for animals to go endangered‚ such as habitat loss‚ pollution‚ disease‚ predation‚ illegal killing‚ and poaching. Habitat loss happens by a mixture of things logging‚ agriculture‚ the building of roads and cities‚ and forest fires. Habitat loss affects China’s giant panda because of the expanding buildings in China. Pollution is affecting fish

are similar‚ but while rainforests have thick canopies of tall trees that block out light‚ jungles allow more light in‚ making it easier for plants to grow. The extra light creates dense areas of plants and vegetation that can be difficult to navigate. Jungles are often found surrounding rainforests. Jungles are home to a wide range of plants and animals. Over half of the world’s species live in a jungle environment. Jungles are usually in warm places with high rainfall. The word ‘jungle’

The classification of animals The Classification of animals : Animal Kingdom can be split up into main groups‚ vertebrates (with a backbone) and invertebrates (without a backbone). When you think of an animal‚ you usually think of something like a cat‚ a dog‚ a mouse‚ or a tiger. All told‚ around 800‚000 species have been identified in the Animal Kingdom -- most of them in the Arthropod phylum. In fact‚ some scientists believe that if we were to identify all species in the tropical rain forests

In centuries ago‚ there were various types of animal species that lived in this world but these species cannot be found for the meantime and forever. There are many efforts had been done in order to preserve endangered species but the numbers of endangered species are still increase rapidly. However‚ there were still numbers of selfish people that did not even concern about the animal species that disappeared. Animal extinction can be defined as animal species no longer stay in the earth as it already

hat are Plants and How did they Evolve: Plants are multicellular‚ photosynthetic organisms‚ adapted primarily for life on land. With a combination of both‚ underground and aboveground structures‚ plants have the ability to absorb water and mineral nutrients from soil while food production is also occurring through the process of photosynthesis. Scientists assume that plants where the cause of evolution‚ adapting from aquatic green algae 500 million years ago. Many essential adaptations would have

For millions of years‚ some animals have been dying out and other species have been appearing. The animals that died out‚ like the dinosaurs‚ may have done so because of sudden changes in the world’s climate‚ or because other species appeared that could hunt them or beat them in the competition for food. Tigers are among the animals that are endangered in Asia. The tiger is native to Asia from the Caucasus and the Caspian Sea to Siberia in the north and Indonesia and even in Borneo and the Philippines
