Well if the ball was to turn, slow down, or speed up, that would be acceleration.
Answer: It is a carbon residue left by a decaying organism.
This picture of the fossil is different from other fossils in terms of its impression. This is an example of compression fossil which is formed by the compression of something on it. The leaves of the tree got stuck on the rock and created an impression on it.
It is different from other fossils in the terms that it does not contains the actual part of the organism, it is just an impression.
Levels of organization helps us (people) to classify the different types of interactions that occur in the environment.
Explanation:
There are six different levels of organization important to the study of ecology - they are: species, population, community, ecosystem, biome and biosphere.
By understanding these relationships we can make informed decisions about policy regarding how to manage our wildlife resources.
For example, Isle Royale is an island located in Lake Superior close to Minnesota which was turned into a national park in the 1930's. The island has a population of moose and wolves. The populations of wolves have dropped to only 3 in 2015 and the number of moose have increased greatly.
By understanding the biology of the moose (species/population level), their predator-prey interaction with wolves (community level) and biotic/abiotic factors (ecosystem level) the park service can make better decisions about how to best manage wildlife populations if the wolves on the island die out.
