Answer:
There is only enough food for a few top level consumers
Explanation:
The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer. Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.
Answer: To help retain warmth throughout the winter, they also grow thicker, shaggier coats, which they shed in the spring when the weather becomes warm again.
Explanation: They want to stay warm.

The correct option is C, THAT IS, OZONE.
CFC acts as catalyst, which enable oxygen to react rapidly with ozone, leading to the destruction of the ozone layers. The whole process is a series of free radical reactions that occur in five stages. A single molecule of CFC can destroy as much as 100,000 ozone molecules. Depletion of ozone layers has grave consequences such as skin cancers, eye damages, etc.
