How might the population of toucans suddenly increase? How might this affect the ecosystem?

1.) A decrease in the population of the animals in the trophic level above it.

2.) It will decrease the population of the animals in the trophic levels below it.

Explanation:

The population would increase if the predator of toucans decreased. This would mean less toucans would die so you would see an increase in their population as they could reproduce more. It will decrease the population of the tropic levels below because an influx of toucans would be more than the other levels could handle.

answer: - few nutrients

high pressure

low temperatures

explanation: 1. few nutrients:   open-ocean zone is located way far from the land, which is the main source of the essential nutrients.2. high pressure: pressure increases by 1 atmosphere for every 10 meters increase in depth.3. ample sunlight: a large fraction of the sunlight is reflected back to the atmosphere from the sea surface. 4. varying salinity: below the thermocline, the water is isolated from the atmosphere so the salinity remains stable over the year.5. low temperatures:   the temperature of open-ocean zone ranges from a low of -2°c to an average of 17°c
