When you heat water, the water molecules begin to move around more quickly. They travel farther apart as they bounce off each other. A volume of hot water has fewer molecules and weighs slightly less than a volume of cold water because there is greater space between the molecules. As a result, heated water has a lower density than cold water. When you combine the two with the hot water on the bottom, the hot water rises to the top, mixing with the cold water and resulting in purple water.

What is most likely to be the first organism to grow in a rock outcrop that has never been home to living organisms?
Yanka [14]

The question is referring to primary succession, which begins with the colonization of living organisms in an area that hasn't had any living organisms before.

This kind of succession begins with microorganisms, and plants such as lichens and mosses.

Given that a rock outcrop is a terrestrial environment, lichens (C) are most likely to be the firsts organisms.

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
