<u>Answer:</u>
<em>Ensuring a sustainable supply of food for the world's fast growing population is a major challenge. Food production is one of the key areas that require action, alongside issues of food consumption, nutrition and food security.
</em>
<em>
It is estimated that by 2050 the world's population will reach 9.1 billion (34% higher than today). Food production will need to increase by 70% to feed the larger and most likely more urban population.1 More food will have to be produced using less land. In addition water and energy will become limiting factors.
</em>
<em>
Added to the challenge is that sustainable food products need to be nutrient-dense to allow people to have a diverse diet that contains a balanced and adequate combination of energy and nutrients to support good health.</em>

Answer:
In the exceptionally cold winter of 1997, Lake Superior froze over between the Wisconsin mainland and Isle Royale. A pack of 8 wolves crossed the ice and reached Isle Royale, an island where they encountered a population of about a dozen wolves. It is estimated that the wolf population on Isle Royale has been isolated for over 100 years (~10 generations). The pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> and if the wolves interbreed with the island population, <u>genetic drift</u> will occur.
Explanation:
The founder effect occurs when a portion of a population (i-e the founders) separates from the old population to start a new population with different allele frequencies. Hence the pack of 8 wolves that crossed the ice would be referred to as <u>founder population</u> in the given scenario.
Genetic drift is defined as change in the allele frequencies in a population due to chance event. As in the given scenario, the pack of 8 wolves that crossed the ice, interbreed with the island population, thus change in the allelle frequency is occuring in the population , hence <u>genetic drift</u> will occur.
Answer:
An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. An erupting volcano is an active volcano that is having an eruption.
A Dormant volcanoes have not erupted for a very long time but may erupt at a future time. Extinct volcanoes are not expected to erupt in the future. Inside an active volcano is a chamber in which molten rock, called magma, collects.
