The carbon in coal and oil comes from plants and animals.
Explanation:
Food chain is the process or method that connects plants and animals to the ecosystem. In this process, herbivorous animals feed on plant for their nutrition and the carnivorous animals feed on the herbivores as their source of food.
Soil plays a key role in this process as it contains many molecules like phosphorous, nitrogen etc. which is taken up by the plants through roots and hence consumed by the animals. This is how energy ascends from one trophic level to another although there is a decrease in each increasing trophic level.
The first one due to the plants using water for photosynthesis. that then produces sugar for the fruits
Answer:
a law is a fact and a theory is still up to debate
Explanation:
you cannot change a law, but someone could conduct a new type of experiment or develop a new technology that could allow they theory to be updated or modified. (not necessarily a large change)
The basis is that a law is taken as fact and theory is close to fact but it should be known that the theory is not fully developed into a law yet.
Answer:
The correct answer is C) The current rate of extinction is high and human activities threaten biodiversity at all levels.
Explanation:
Extinction is a natural process in which certain species extinct because of the lack of adaptability to the changing environment or by other reasons but today extinction rate is increased by human interference.
In a study on fossils, it was found that earlier on every 10,000 species 2 gets extinct every century and when the extinction that occurred during the last century was calculated then it was found that approximately 500 species got extinct in past 100 years which was largely high then it would be in case of natural extinction.
This extinction rate is increased because of habitat loss of species by human interference and by threatening biodiversity at all levels by human activities. So the right answer is C.
