1. In the carbon cycle photosynthesis producers convert CO2 into sugars, then during respiration sugars are converted back into co2. After that burial occurs and some carbon can be buried. Furthermore, extraction occurs and human extraction of fossil fuels brings carbon to earth's surface, where it can be combusted. Once that occurs the exchange CO2 in the atmosphere and CO2 dissolved in water are continually exchanged. Finally, combustion converts fossil fuels and plant material into CO2 and then the cycle starts all over with photosynthesis.
2. A biome is a large natural community of plants and wildlife in a major habitat, like a tundra, desert or forest. In addition, it is made up of all the habitats of a community that make up comparable …show more content…
Both logistical and exponential growth are an increase in the population size. Logistical population growth has a constant growth rate. It is more constant than exponential growth. Logistical growth usually starts with exponential growth and then the population reaches the carrying capacity and the growth stabilizes and becomes more constant. In exponential population growth, the population growth accelerates over time. It starts slowly, but grows quicker and quicker as the population increases. They are both and increase in population, but they are very different shapes when represented by a graph.
4. Population is a group of the same species or group. It is a group of organisms of one species that interbreed and live in the same place at the same time. Metapopulation are groups separated from groups of the same species. Metapopulations is a population of populations.
5. The individualistic view of community suggests that population inhabit a place simple because it meets basic environmental requirements. It does not look at how populations interact or need other populations. The holistic view of communities sees all populations as one super organism. If one population is damaged it affects the entire
