Proteins have up to four levels of organic structure.

1.Primary structure - the linear arrangement of amino acids.

2. Secondary structure - areas of folding or coiling within a protein.

3. Tertiary structure - the final three dimensional structure of a protein.

4. Quaternary structure - non covalent associations that bind multiple polypeptides into a single larger protein. E.g. hemoglobin has four polymers, two alpha and two beta chains. They are non covalently bound to each other to form a single large protein - hemoglobin.

Although animals CANNOT digest cellulose directly, some animals have a symbiotic relationship with ________ living in the small

Lesechka [4]

Answer: microorganisms

Explanation: No animal has the ability to digest cellulose directly.

Most animals such as horses and termites cannot directly digest cellulose. The animals have a symbiotic relationship with bacteria in the intestinal tract. The symbiotic bacteria acts on the cellulose and secrets the necessary enzymes (cellulase) to digest cellulose in the intestinal tract. An example of such microorganism in a symbiotic relationship with animals that facilitates the digestion of cellulose is Trichonympha

Are there more producers or consumers in and ecosystem? Why?

Dafna1 [17]

Producers or autotrophs

Autotrophs obtain energy by the process of photosynthesis. Any living organism need energy to survive and autotrophs are no different. Two types of autotrophs are present and they are Photoautotrophs and Chemoautotrophs. The Photoautotrophs rely on the energy produced during the process of photosynthesis and the Chemoautotrophs get their energy from most of the inorganic substances. Phtoautotrophs actually get their energy from the sunlight and then convert it into reusable form. In case of Chemoautotrophs ammonia is an important source of energy for them.
