1. White-breasted nuthatches and downy woodpeckers both eat insects that hide in the furrows of bark in hardwood trees. The downy woodpecker searches for insects by hunting from the bottom of the tree trunk toward the top, whereas the white-breasted nuthatch searches from the top of the trunk down. These hunting behaviors best illustrate which of the following? Competitive displacement of resources for the downy woodpeckers

Exploitative interaction, resulting in declined diversity

Competitive mimicry that will result in reduced resources

Coordination of resources, allowing for access to both species

2. As prey populations increase slightly in size, predator populations will at first

decrease greatly

decrease slightly

increase greatly

increase slightly

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

the answer is c on e2020, bud.
