Answer:
The correct answer is B-typically grow slower than in pure culture
Explanation:
In nature, microbes experience lots of challenges like challenges to get space, to live, to get food, to adapt to the changing environment, to get protection from their pathogens and predators, etc. So these all challenges affects the growth rate of microbes.
In pure culture only one type of bacteria is grown on a nutrient-rich media and a steady environment is given to them to grow. In pure culture, there are no predators and competitors for microbes.
So all this provide favorable condition for a microbe to flourish in a pure culture so the growth of an organism in pure culture is higher than in nature. So the correct answer is B.
Answer:
X: Producers undergo photosynthesis;
Y: Decomposers return carbon to the soil and release waste
Explanation:
Producers, for example, a clover, will take the CO2 in the atmosphere and use it in photosynthesis to turn it into nutrients, then the consumers, for example, a deer, will eat the producer to gain nutrients. After the consumer dies, the decomposer, for example, fungus, will eat away at the consumer, releasing CO2 into the atmosphere. Then the cycle keeps going.
Answer: They all eat new twigs, grasses, and leaves
