Why does the earth have different layers?

Biology
1 answer:
Aliun [14]3 years ago
6 0

Answer:

The earth has different layers because as it formed, the lighter parts (like continental crust) floated to the surface, and the really heavy parts (like iron and nickel in the core) sank to the middle. It is just like when you mix oil and water: the oil will float to the surface because it is lighter (or less dense) than the water.

Moose make mating calls to locate potential mates
Bingel [31]
<span>Moose are generally docile towards humans, but may become more aggressive during the mating season of September through October.The name "moose" comes from the Native American word "Moswa," which translates to "twig eater."On average, moose live 10 to 15 years in the wild. Moose are considered fully mature at 4 to 5 years of age.Moose are remarkably agile for their size, capable of running at speeds of up to 35 miles per hour.Moose are capable of swimming up to 10 miles without stopping.Moose are unlike many other deer species in that they are mostly solitary animals. However, strong bonds exist between mothers and calves.The moose population in North America is estimated to be fewer than 1.5 million, with 1 million in Canada alone. Up to 200,000 are estimated to live in Alaska.Moose are herbivores, and eat a large amount of terrestrial vegetation, but they also must need to consume a good amount of aquatic plants which provide moose with sodium.Moose must consume 9770 calories per day to maintain their body weight.A moose will eat up to 70.5 pounds of food a day.If a bull moose is castrated, he will shed his current set of antlers and grow new, deformed and misshapen antlers which will never be shed again. These antlers are often called "devil's antlers" and are the source of several Native American myths. In rare cases, cow moose may grow antlers due to a hormone imbalance.Because of their heavy bodies suspended by spindly legs, moose are especially dangerous when hit by passenger cars. If you are driving in an area where moose are plentiful, use caution and pay attention at all times.<span>Moose antlers may weigh up to 70 pounds, and measure 6 feet across.</span></span>

Which best describes the role of a primary consumer in a food web? Carnivore that feeds on producers Herbivore that feeds on pro
Andreyy89

Hello there! :D

First of all, let me put in a picture of a food web for you to reference!

(you should see it below)

Let's talk about how a food web works. Many science books will tell you that a food web is like a pyramid, but this could not be more false! A food web shows the relationship between consumers and producers within any given ecosystem. Sometimes it is not as simple as a line or diagram, because some animals can be both primary, secondary, and teriatry consumers (us!!).

Look at the food web below, and see the grass that eventually is eaten by the grasshopper. We know that the primary source of energy for plants is the sun, which is not included in the web, but just so you know for reference for future questions. What thing in this web supplies the energy for the entire food chain? The producers! This would be the grass and the planktin you see in the web.

What is the difference between primary and secondary consumers?

Glad you asked! Primary means first, and secondary means second. Primary consumers are cosumers that directly eat producers. That would be the grasshopper or the fish! Secondary consumers recieve energy from producers from primary consumers. Examples of these are the mouse and lobster.

So, the best answer to the question above is a Herbivore that feeds on producers, because a primary consumer is a consumer that eats producers directly, and most producers are plants! Answer "B".

I hope this helps you and you have a wonderful day,

Kai xx
