Answer: This is because sharks are pregnant for 6 months to 2 years. Which decreases shark population due to slow birth rates. This also effects female sharks health die to the stress of carrying many sharks for up to 2 years. Most sharks die before or after giving birth. Overfishing for sharks is rapidly decreasing the shark population due to slow breeding but many fisherman. Less females and males are able to mate and sharks are pregnant for so long that the female has a high percentage of getting caught. In the long run more and more sharks are being killed each year which decreases sharks population for obvious and non obvious reasons.
Explanation:
OXYGEN will most likely “Accept electrons” hope I helped!
It would become a metamorphic rock.
Marine organisms at higher trophic levels will have higher concentrations than animals in lower trophic levels. This is because mercury is not easily eliminated from these organisms so the concentration can increase as you go up the food chain. For example, one fish eats five shrimp each with one molecule of mercury, the fish now contains five molecules. If a larger fish eats several fish with five molecules of mercury then the concentration increases through the trophic levels.
Answer:
Crop intensification can be defined as the methodologies/procedures used to increase crop productivity (i.e., food, biofuel, fiber) in the same unit of land. These methods include relay intercropping, successions crops and the use of organic materials in order to increase the fertility of the soils (and therefore plant growth)
Explanation:
Crop intensification refers to the techniques used by farmers around the world aimed at increasing crop productivity (for example, wheat yield, cotton fiber production, etc.) These systems of crop intensification mainly include relay intercropping and successions crops, which increase the fertility of the soils (especially after oilseed crops) and crop resilience to climate change. The addition of organic material may also result useful to increase the plant growth (i.e., crop production) and agricultural sustainability by minimizing available resources such as, for example, water availability, chemical fertilizers, etc.
