How is control of a disease such as bubonic plague complicated by the fact that it spreads across multiple animal species?
Answer:
Bubonic plague outbreaks are controlled by pest control and modern sanitation techniques. This disease uses fleas commonly found on rats as a vector to jump from animals to humans. The mortality rate hits its peak during the hot and humid months of June, July, and August.
Explanation:
Answer:
The fact that a disease spreads through multiple animal species creates problems in its eradication since it is necessary to look for more than one strategy for disease control, additionally this causes the disease to expand at a more dizzying pace.This situation also causes the disease to expand geographically and increases the likelihood of infection in humans.

What effect does a rapidly changing environment have on the natural selection of organisms in a species?
A. Organisms will decrease their reproductive rate.
B. Species with little genetic diversity will adapt most quickly.
O c. Species that cannot adapt quickly enough may become extinct.
• D. Organisms will increase their rates of mutation to adapt to change.
Rapidly changing the environment of organisms can result in them going extinct if they refuse to adapt quickly enough.
Natural selection and the environmentOrganisms need to adapt to new environments.
Thus, changing the environments of species rapidly means that the species either catch up by adapting as rapidly or risk going extinct.

If the grass contains 100,000 kcal of energy, the energy a fox will obtain from eating a bird is 1,000 kcal.
What is Calorie?This is defined as a unit of energy and it decreases as it moves up the food web in the ecosystem.
The organisms only derive 10 percent of the energy when the feed on others. In this case, the grass has 100,000 kcal of energy which when eaten by the bird will be 10 percent which is 10,000 kcal. When the fox eats the bird it becomes 1,000 kcal.

Describe how a lake might become a forest in a period of 100 years.
Lake might become a forest in a period of 100 years by the process of hydrosere.
What is hydrosere?
Hydrosere is defined as the primary succession that develops in aquatic atmospheres such as lakes and ponds.
There are different stages in the succession from lake to pond. such as the initial stage of succession is phytoplankton, and zooplanktons which pioneer colonizers.
Rooted submerged stage is another stage which suitable for the growth of rooted hydrophytes like Elodea, Myriophyllum, etc.
Floating stage is the third stage where submerged and floating plants grow intermingled but after soon the submerged plants are replaced completely by the dead plants deposits at the bottom.
Reed-swamp stage is 4th stage where the plants of this community are rooted but most parts of plant shoots remain exposed to air.
Sedge meadow stage is 5th stage where further decrease in water level changes the nature of substratum and grasses grows on the area.
Woodland stage is 6th stage where some shrubs and later medium sized trees form open vegetation or woodland tress grows.
Forest stage is the final stage or climax community stage which is invaded by several trees which further develop into forest.
