The type of organisms that take energy by eating up other organisms in an ecosystem are called 'CONSUMERS'. Now these consumers are further divided into three major classes:
1. Primary consumers: this type of consumers feed directly from the producers (plants) and they only eat grass, leaves, vegetables, etc. Such animals are also called herbivores. Example: rabbit
2. Secondary consumers: these are the animals that eat up primary consumers (animals that feed only on plants). These animals are called carnivores. Example: snake
3. Tertiary consumers: animals that eat carnivores which eats a herbivore are called tertiary consumers. They can be completely carnivore or omnivore (who feed on animals and plants both). Example: humans (they feed on animals and plants both)
I'd say
B. Contour Farming
since it's planting on a flat surface and creating w/ridges to help prevent water from taking the crops away
The correct answer is It would be more difficult for DNA to unzip since it would require more energy to break the bonds.
That is because it would most probably be a covalent bond and such a bond is stronger than a hydrogen bond which means that more energy would be needed to break it.
Answer:
The correct answer is - they are both systems that are performing similar functions.
Explanation:
In the given question there are two different entities that do a similar kind of work or perform similar functions, however, the systems are different as one system involves the manpower of a worker whereas the other system involves the high power of a bulldozer.
The work is similar but the amount of the work varies as manual work done by a worker is less in comparison to the bulldozer.
