Question

1. Explain why areas of the equator are warm and moist and why areas near 30 degrees are warm and dry.
2.How are the terms NICHE and HABITAT related? Why does describing an organism's niche give you a lot more information that describing the organism's habitat?
3.Why are niche's important in smaller, confined habitats such as a cave or a single tree?
4. Many cells make ________. Many related organs that work together make a(n) _____________.
5.Give an example of a stimulus and response that may be exhibited by a shark.
6. How does bee development differ from a roaches?

Answer 1

4. Many cells make tissues. Many related organs that work together make an organ system.

Answer 2

6. Bee development differ from a roaches because a bee has four stages before being an adult, while a roach has 3 stages. Bees goes from being and egg, then a larva, then a pupa, and finally the adult stage. Roaches goes from being an egg, then a nymph, and finally an adult.

Answer 3

1.Axial tilt.
As the planet orbits the Sun, the equatorial areas get more constant sunlight. Because the planet's axis is tilted ~23.25° (this means it leans a little away from straight "up and down"), certain parts of the world are farther away during certain parts of the year. The equatorial areas, however, are always in more-or-less direct sunlight, which causes them to be warmer.
It's also why we have seasons!

Answer 4

A habitat is the location of where the organism lives; the niche is the role which the organism plays in its own enviroment.

Answer 5

In biology or ecology, a niche is a specialized area in which evolution optimizes certain species for. Some examples of niche are predator, grazer, hunter-gatherer, scavenger, and parasite. Examples of animals occupying those niches are lion, deer, human, vulture, and roundworm. There are many different ways to determine and list niches, including many possible levels of specificity in describing niches.

The first niche was likely occupied by chemotrophs, microorganisms that gained energy from the environment by oxidizing inorganic compounds like sulfates. A couple billion years later, chemotrophs were followed by photosynthesizers, or producers/autotrophs, which gained their energy by using the sun's rays, carbon dioxide, and water to generate ATP, the energy currency of the cell. These organisms were cyanobacteria, and they persist in large numbers to this day. More modern autotrophs include trees, flowering plants, and vines.

Answer 6

3. i think because of competition

Answer 7

5 The traditional view of shark intelligence is that they have none to speak of. It was taken for granted that a given stimulus would generate in any shark a specific, un-learned response. This response would be performed the same way, time-after-time, independent of context or probable survival value. In short: sharks were deemed to be little more than mindless automatons.
