The correct answer is that a population overshoots the carrying capacity and environmental pressures and shortfalls begin to exert their effects. A certain area of environment only has limited resources such as food, water, habitat, etc. These limited resources are called the carrying capacity of the environment. If the population exceeds the carrying capacity of the environment, there will be not enough resources to sustain the population therefore members of the population will die and the overall population number will crash hence the term <em>population crash. </em>
Well if they were identical to their parent plants then the plants reproduced asexually (asexual reproduction) meaning that the offspring came from one parent making the offspring have the same genetic make up, like clones
The green house effect is when their is too much pollution in the air. Cars, factories and industries cause a lot of pollution in the air which then causes the ozone to thin out which causes it to get hotter because the ozone is a layer that keeps the temperature not too hot or cold
Carbon cycle refers to an array of procedures by which the compounds of carbon are interconverted in the environment, comprising the inclusion of carbon dioxide into living tissue by the process of photosynthesis and then getting back into the atmosphere via respiration, the burning of fossil fuels, and the decomposition of dead organisms.
The following are the steps that illustrate how the carbon cycle functions:
1. Carbon enters the atmosphere as carbon dioxide from combustion and respiration.
2. The absorption of carbon dioxide takes place by the producers to manufacture glucose in photosynthesis.
3. The animals feed on the plant passing the carbon components through the food chain. The majority of the consumed carbon is exhaled in the form of CO2, which was produced at the time of aerobic respiration. The plants and animals die eventually.
4. The dead plants and animals get dissociated by the dead organisms and return the carbon present in their bodies back to the atmosphere as CO2 by the process of respiration. In certain occasions, the dead plant and animals get converted into fossil fuel, which is available in future for combustion.
