Biological pest control methods supplement but cannot replace chemical pest control methods.t/f

Answers

This is false. Farmers of organic food have been doing this for a whileand it has become a trend. Food grown this way is usually a lot moreexpensive but the evidence that the food made in this manner ishealthier still up for debate as inconclusive results have been found,pointing out that there's really not that much of a difference.

Answer:

False

Explanation:

Biological pest control methods are used to control the population of pest below a level where it cannot damage the crops. Instead of using chemicals (which lower the soil quality), living organisms (which are predator, parasite, herbivore etc.) are introduced in the crop field to keep a check on population of damaging pest or weeds

This is an organic method of gardening where a beneficial organism is chosen to control the harmful pest

How do the characteristics of living things contribute to an organisms survival

Answers

Any characteristic, whether a physical trait, a behaviour, a physiological adaptation etc can make an organism more or less likely to survive in a particular environment.

A dark colour could help a rabbit survive if it lives in a dark forest, because predators can't see it so well, but it would be less likely to survive in the arctic, where the environment is all white and it would show up.

In terms of the characteristics, think about: does it help the organism get food? Does it help protect the organism from predators? If it does, that organism is more likely to survive, and pass the characteristic on to it's offspring. If a bacterium has a characteristic of not being killed by antibiotics, this will help it to survive and breed.
