Answer:
0.1 degree per annum
Explanation:
There are 30 years between the years 2020 and 2050. If the average temperatures increase by 3 degrees Fahrenheit in 30 years, then the rate of change of temperature equals the ratio of the total increase in temperature and the number of years.
Rate of change = 3/30 = 0.1
<em>Hence, the rate of temperature change is </em><em>0.1 degree Fahrenheit </em><em>annually.</em>
Answer:
100 beetles are present in per hectare if they are uniformly distributed.
Explanation:
If the population is uniformly distributed, so the population of beetles i. e. 11500 is divided by 115 gives the result of 100 beetles per hectare. If the environment is suitable for the growth of beetles, the carrying capacity of beetle population is about on million per hectare. They grow very fast if there is plenty of water and food is available for beetles but their population decreases when drought occurs in the area.
