Ecology EQ’s 2. Abiotic and biotic components influence each other. For instance‚ temperature (abiotic factor) can make plants (biotic factor) reproduce more or reproduce less. Also water‚ an abiotic factor‚ has an effect on how animals‚ a biotic factor‚ survive in certain areas of the world. 3. Because a different niche allows multiple species of organisms to coexist. If all organisms had the same niche‚ then there would be heavy competition for food‚ shelter‚ etc. Having different niches gives

The three-domain system is a biological classification that divides cellular life forms into archaea‚ bacteria‚ and eukaryote domains. It emphasizes the separation of prokaryotes into two groups‚ called Bacteria and Archaea. These two groups and eukaryotes each came from separate ancestors with poorly developed genetic make-ups. This classification system recognizes the fundamental divide between the two prokaryotic groups. Archaea appear to be more closely related to eukaryotes than they are to

Lemurs are a type of primate that are native to Madagascar. There are many different species of lemurs and they are all endangered. There are several reasons why lemurs are facing extinction; lemurs are being put at risk by deforestation‚ hunting‚ and climate change (Dunham et al.‚ 2008). Deforestation in Madagascar is especially significant in affecting lemurs. Deforestation leads to habitat loss and habitat fragmentation‚ which may have negative consequences for lemurs (Craul et al.‚ 2009). Lemurs

Task one A). How do living things interact? Living things find a way to live off the land. Not with artificial flavouring or stuff like that. But it may not last unless we take good care of it. Living things interact by: 1). Viruses Learn about viruses and their surroundings‚ and how they are created. What is a Virus A virus s a small‚ NONLIVING particle that invades and then reproduces inside a living cell. Viruses are considered nonliving because they are not cells. They cannot: * use energy
