Ecological succession is the gradual process by which ecosystems change and develop over time. Nothing remains the same and habitats are constantly changing.
There are two main types of succession, primary and secondary.
Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before.
Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat.
Answer:
We depend on them to convert carbon dioxide into oxygen. And also for food energy.
Explanation:
Answer: The correct answer is- bone structure of the baleen whale and the hummingbird share common ancestor.
Bone structure of the baleen whale and the hummingbird are the homologous organs.
Homologous organs can be described as the organs of different animals, which possess same basic structure but perform different functions.
For example- The flippers of a whale and forelimb of man, bone structure of the baleen whale and the hummingbird.
Baleen Whales and hummingbirds have a basic tetrapod skeletons, which is inherited from a common ancestor. But their bodies have been modified and they have lost parts through natural selection. This results in different adaptation in the form of their respective lifestyles over many years.
Answer:
The correct answer is - autonomic (visceral) reflexes.
Explanation:
Autonomic or visceral reflexes is somewhat similar somatic reflexes but visceral reflex takes place in various soft tissues and muscles present in soft organs such as digestive, cardiac muscles, reproductive muscles, and others.
Visceral or autonomic reflexes include activation of smooth muscles, glands, and dilation of pupils, vomiting, defecating, sweating, blood pressure and many more body function regulating.
Thus, the correct answer is - autonomic (visceral) reflexes.
