Persistent chlorinated hydrocarbon pesticides persist in the environment and accumulate in the foods chain causing harmful effects on the environment including posing a threat to humans health in the long term. Nonpersistent organophosphate pesticides are more toxic than the former but degrade after a short life span. Therefore they cause immediate harm in case one is in contact with them.
The fact that they do not accumulate in the environment, they are more favourable than chlorinated hydrocarbon pesticides. Chlorinated hydrocarbon pesticides will affect several generations due to their accumulation in the environment. However they don't need to be re-applied hence are less expensive
The correct answer is option D, that is, it will increase the amount of carbon in the soil and increase the amount of carbon dioxide discharged by decomposers.
One of the ways to manage the garden is to utilize mulch, the mulch minimizes the contact between the soil and the organic matter so that the species will consume more time to dissociate it. The mulch will decompose and its nutrients will be discharged to the soil, however, it takes place very gradually, and enhances the organic matter in the soil.
If the mulch is left in the garden for a year, then the soil will be conserved and supplied with nutrients and this process will retain carbon in that garden. The sources of mulch can be leaves, grass, straw, or composted garden waste.
Euglena is a protist that exhibits both plant and animal characteristics, therefore they have the ability to
live a double life. When there is sufficient sunlight, they are green and
photosynthetic like plants and they can make their own food. They use their chloroplasts
to produce sugars by photosynthesis. Also, <span>in the absence of sunlight, when they cannot produce their food, they consume smaller living organisms such as
amoeba like the animals. </span>
