Answer:

All matter is made up of tiny particles called <em><u>a</u></em><em><u>t</u></em><em><u>o</u></em><em><u>m</u></em><em><u>s</u></em><em><u>.</u></em> Atoms are made up of three subatomic particles known as <em><u>proton</u></em><em><u>,</u></em><em><u> </u></em><em><u>neutron</u></em><u> </u>and<em><u> </u></em><em><u>electron</u></em><em><u>.</u></em> Protons and neutrons are located in the <em><u>nucleus</u></em><em><u>.</u></em>

The nucleus is dense and takes up very little space within the atom. All protons have a <em><u>positive</u></em><em><u> </u></em>charge and have a mass of about 1 amu. All neutrons have no charge or are <em><u>neutral</u></em> and have a mass of about 1 amu.

Electrons are located in the area known as electron cloud. Electrons orbit around the nucleus and have a <em><u>negative</u></em> charge

*Name three ways the organisms in a food web get energy.
Anuta_ua [19.1K]

Answer:

1.)photosynthesis, chemosynthesis, and the consumption, this is three ways how organisms in a food web gets energy.

2.)Cells use energy in order to grow, regulate metabolism and reproduce. This energy is obtained from a source such as food molecules or light from the sun, and through processes like glycolysis, the citric acid cycle and oxidative phosphorylation, an energy-rich molecule is then created. The cell can then use the energy in the protein molecule to help it function.

3.)Food webs vary according to habitat, but all food webs have some things in common. Primary producers make up the base of a food web. Phytoplankton . Consumers cannot make their own food so they need to get food from other sources. This means that we are close to being a consumer because we cant make up our own food and we have to get other food from animals and plants and our drinks from many things that go through the food web.
