List some general characteristics of producers and list a few examples.
arsen [322]

A producer is like... a green plant or bacterium (plural for bacteria) and it's part of the first level of the food chain. Phototrophs and chemotrophs are two major producers. Phototrophs use the energy from the sun to convert carbon dioxide into carbohydrates, in other words, photosynthesis. Chemotrophs are almost microscopic- they are found in places where water and light are scarce (or rare) or even not there at all.

Sorry if this isn't any help... I'm trying my best, I don't know much. But if it does help, you're welcome! Have a nice day!

xeze [42]
Energy coupling is the transfer of energy from the energy forming step to the biomolecule forming step. The energy forming step is called catabolism wherein the complex molecules are broken down and releasing energy. The energy produced is then used the process called anabolism which produces biomolecules such as proteins.

Give an example in the human body of a molecule cotaining ionic bonds
Lemur [1.5K]
<span>An ionic bond is a complete transfer of electrons from one atom to another. This generally happens between atoms that have opposite electronegativity. This means one has very few atoms in their outer shell, while the other has many. A common example of an ionic bond is that of salt, with Na and Cl. Sodium has one electron in its outer shell, in which it transfers to chloride to make an ionic bond.
</span><span>
Ionic bonds are usually found in dry forms such as salts and are found in compounds throughout the human body. Ionic compounds are generally water soluble.</span>
DNA<span> - As you recall, DNA is formed in the shape of a double helix. The double strands of DNA are held together by hydrogen bonds. Each single strand has a backbone made of sugar and phosphate, as well as either a purine (adenine or guanine) or pyrimidine (cytosine or thymine). Each purine is connected to a pyrimidine through a hydrogen bond, giving the double DNA strand strength, and flexibility. This bond holds the two sides of DNA together, each bond contributing to the overall strength of DNA. When DNA is replicated, special enzymes known as DNA helicase "unzip" DNA and these bonds are broken so the two strands can be individually replicated.</span>

Which type of process occurred in the ecosystem that was affected by the 1988 fires in Yellowstone Park, which destroyed most of
Liono4ka [1.6K]

The correct answer is B. Secondary succession

Explanation:

In ecosystems, secondary succession occurs as certain events such as fires cause vegetation to temporarily disappear from one area. However, as soil is not affected negatively, vegetation grows again after some time, which means there is a secondary growth of vegetation and changes in the structure of an ecological community.

This term applies to the situation in the 1988 fires in Yellowstone Park because the fire destroyed the vegetation in the zone temporarily, but as the soil was intact after years or decades the vegetation will grow again, although this might implied changes in the ecosystem.
