pangaea cause of breaking up was a rift that developed between eastern U.S. and Western Africa
The most accurate method is to use a pyramid of energy to show the transfer of energy between trophic levels
nekton animals are animals such as dolphins, fish all kinds of fish like tuna and different fish, nekton animals are sharks and whales to all kinds of them it really don't matter what kind of shark or whale or fish it is.
The vertical distance between a crest and trough is the peak to peak amplitude of a wave. In comparison, the vertical distance from a midpoint to a crest or a trough is called the peak amplitude.
one that fed through a food web
Archaeopteryx is considered the 1st Bird.
It was from a long line of Avian dinosaurs which are very very closely related to the Raptor family of Therapod Dinosaurs.
The morphology of avian dinosaurs and modern birds are so similar many scientist class birds as avian dinosaurs.
Single celled organisms.
age of mammals
A Food Chain.
Based on the popular theory that the dinosaurs went extinct due to the impact of a large asteroid, scientists think that the asteroid caused large amounts of debris to fly into the atmosphere, blocking out the sun. This caused global temperatures to drop, thus freezing the plants. In addition, without the sun the plants could not carry on photosynthesis, which caused them to die.
Many dinosaurs have birdlike traits. The basic body plan of theropods (the two legged carnivores) is somewhat birdlike. However some of these are especially birdlike. Among these are Archeopteryx, which is widely attributed to be the earliest known bird and clearly has traits of maniraptoran theropods. A number of maniraptorans such as Velociraptor are now known to have had large, well-developed feathers. One relative, Microraptor, is believed to have been able to glide between trees.
when energy is transferred to a higher trophic level some of the energy is trued into heat and is released
how were land organisms affected by the breakup of pangaea
Yes, the Rocky Mountains are in the western United States.
