A cow eats plant material like hay and grass that is full of cellulose. Cellulose is very hard to digest, so the cow relies on bacteria and other organisms that live inside them to break down the cellulose into a form from which they can extract nutrients. The ruminant stomach is vastly different from your own digestive system. Without cellulose-digesting bacteria, cows wouldn't be.
Question 1: The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.
⇒
The carnivore consumes meat, or other animals such as the herbivore. It's the last.
⇒
⇒
Therefore the answer is
B.

Question 2: I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is
still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.
Populations of organisms that have sigmoid growth curves
limited by the carrying capacity are called K-selected.
Species are divided into two selected species, R-selected
species and K-selected species. K-selected
species are <span>also called K-strategist. These are the species whose populations vary at or near the <span>carrying capacity <span>(K) of the </span></span>environment<span> in which they live.</span></span>
How could you use biotechnology to protect a plant from insect damage? Insert genes that produce anti-insect chemicals into the plant. So B.
Answer:
Explanation:
Exceptions to cell theory are
1. Viruses: They contain only genetic material. Protoplasm is absent. Active or show signs of life only in a living cell
2. Coenocytic organisms: Vaucheria and fungi belonging to Phycomycetes are filamentous with continuous protoplasm and many nuclei, that is the filament is not divided typically into cells, with single nucleus that undergo division periodically.
