Answer:
A) The scientific study of the distribution and abundance of organisms and their interactions with the environment.
Explanation:
Ecology is the part of biology that is concerned with the study of the relationships established between living beings and theirs with the environment in which they live. It is a term derived from the Greek that was formed from the junctions of the words "oikos" and "logos", which mean, respectively, home and study. Thus, the term Ecology refers to the study of the “home” of every organism on the planet.
The term Ecology was first used in 1866 by a German zoologist named Ernst Haeckel, in a work called "Generelle Morphologie der Organismen". In this work, the author defined Ecology as "the scientific study of the interactions between organisms and their environment."
A mixture is made from two or more substances that are different and are not joined. A compound is a substance formed when two or more elements react with each other to form chemical bonds between their atoms
The discharge in the stream at a given cross-section and the level of the stream is described by a rating curve<span>. Average velocities and the cross-sectional area of the stream are measured for a given stream level. The velocity and the area give the discharge for that level. After measurements are made for several different levels, a </span>rating table<span> or rating curve may be developed. Once rated, the discharge in the stream may be determined by measuring the level, and determining the corresponding discharge from the rating curve. If a continuous level-recording device is located at a rated cross-section, the stream's discharge may be continuously determined.</span>
Answer: D. Secondary
Explanation:
An ecological disturbance is a circumstance caused by an agent that can be of biological or non-biological origin. The agent is capable of bringing negative changes to an ecosystem. Fire is an example of ecological disturbance. In the given situation, the forest burns down the trees are an example of the direct interaction of fire with the trees; therefore, it is a primary disturbance. Nevertheless, this interaction led to the loss of habitat of animals forced to move to other areas as the fire burned the trees. It is called secondary disturbance.
