The best kind of model for the scientist to use is an interactive model of the planets' orbits on a computer.
<h3>What is the law of orbits?</h3>
Kepler's first law, also known as the law of orbits, describes the shape of planetary orbits. According to this law, the planet's orbits around the Sun are elliptical, despite having very small eccentricities.
For this reason, it is necessary to know all the orbits of the planets in an interactive way, since according to Kepler's law, the orbits decrease over time.

energy enters an ecosystem through photosynthesis. By feeding on plants and on one another, animals play an important role in the movement of the matter/energy though. they also influence the quantity of plant and biomass present. so the anwser is D, secondary consumers to tertiary consumers
1. Exchange materials with its environment efficently
The answer to your question is A. Higher latitudes receive less radiation due to the curvature of the Earth.

Veins contain valves that ensure blood flows in only one direction. Valves also help blood travel back to the heart against the force of gravity.
Hope this helps.....
