Answer:
D. Fruit trees, birds/monkeys, tigers
Explanation:
Fruit trees are the primary producers and produce fruits and other plant parts as food for birds. Monkeys are omnivorous and derive nutrition from eggs of birds or fruits, seeds and other parts of the plant. Tigers are top consumers and are carnivores as they feed on monkeys and even birds. Therefore, the given ecosystem may have the following food chain:
Fruit trees (first trophic level and producers)----> birds /monkeys (second trophic level and first consumers)---> tigers (third trophic level and top consumers).
The change from a high to a low pitch is a phenomenon known as the Doppler Effect or the Doppler shift. Sounds come in waves and are known as sound waves.
The Doppler Shift or effect is relevant to the location of the person who is hearing the sound. When a person is moving closer to the source of the sound, the wavelengths become shorter and they become low pitch; but when the person moves away from the source of the sound, the wavelengths become longer and become high-pitched.
Answer:
The fossil record shows that early species of horses were generally small in size, but many lineages since about 30 million years ago exhibit substantial change toward an increase in size.
Explanation:
It was demonstrated that variation in size as well as in diet during the last millions of years, were consequences of different climatic and geographic changes.
The fragmentation of horses´ populations was associated with habitat heterogeneity and to a new tendency for colonizing new areas that were not accessible before that time.
When great plains with grasslands appeared, horses moved to these new areas, reproduced, and got bigger and taller with time. The new species became even bigger. They evolved from small mammals that fed on shrubs in the forests, to the big current horses that graze on the open plains.
It tells you that a large amount of their brain processing is oriented towards laterally than can humans and need to be able to process movement to detect predators and prey, they need more processing power for interpreting visual <span>signals.</span>
