Answer:

A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things

To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains.

C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.

Which two statements summarize a way that an other-feeder gets food?
maksim [4K]

Answer:

B. Sphagnum moss takes in energy from sunlight.

D. Euglenas carry out photosynthesis.

Explanation:

According to the question, "a self-feeder" means an autotrophic organism i.e. an organism that produces or obtains food by itself. The process by which an autotrophic organism obtains food is referred to as PHOTOSYNTHESIS. Photosynthesis entails the synthesis of food in form of organic compounds in the presence of sunlight.

Based on this, Euglenas, which is a plant-like protist, carrying out photosynthesis and Sphagnum moss, which is a lower plant (bryophyte) taking in energy from sunlight in order to perform photosynthesis are two examples that describes a "self-feeder"

sergey [27]

Answer:

Atoms of the same chemical element do not always have the same mass because, although the number of protons in the nucleus is the same for all atoms of the same element, the number of neutrons is not. Most elements as they occur naturally on earth are mixtures of several isotopes.
