The correct answer is A. An oak tree
Explanation:
The term "primary producer" is used to describe organisms that can produce their own energy without feeding on others, this includes plants and algae that produce food and energy through photosynthesis using light and other inorganic compounds. Additionally, the primary producers can be identified because in ecosystems they are always on the first level and they are eaten by others.
According to this, the one that is a primary producer is an oak tree because this is a type of plant and therefore can produce its food through photosynthesis different to others that need to feed on other organisms to obtain energy.
The earth's distance from space is 0 because it is in space
Answer:
Summary:
Explanation:
Around 1 million years ago, the first of a few glaciers moved south into what is now Ohio. Approximately 2/3 of the state was covered to their maximum extent. Glaciers scraped a lot of Ohio's surface, including its bedrock. They also left deposits of clay, sand, gravel, and rock as they melted back. During this period, humans appeared in what we now call the "Old World." At some point around the end of the Quaternary Period, groups of people migrated to the "New World," and eventually reached what would later become Ohio.
Answer:
Side lengths
Angle measures.
Explanation:
Polygon refers to two dimensional shapes that is created by straight line segments connected to form polygonal circuits. When rotated they have the same lengths and angle measures because it is equilateral and equiangular and rotated at 360 degrees.
This means that it has equal side lengths and equal measure angles.
The number of lines of reflection symmetry is the same as the side of polygon because it has the same length.
For example, Pentagon is a five sided polygon, when rotated, it has five lines order of symmetry. The angle of rotation is 360 degrees, therefore 369 degree is divided by the five lines of symmetry which is 72 degrees.
