An aquatic ecosystem was rich in benthic microalgae and sea grasses. over the years, industrial pollutants have reduced these populations considerably. how would this affect the ecosystem? a) there would be no energy produced in the system. b) there would be more energy available in the ecosystem. c) it will increase the number of organisms at higher trophic levels. d) there would be less energy transferred to the higher trophic levels. an aquatic ecosystem was rich in benthic microalgae and sea grasses. over the years, industrial pollutants have reduced these populations considerably. how would this affect the ecosystem? a) there would be no energy produced in the system. b) there would be more energy available in the ecosystem. c) it will increase the number of organisms at higher trophic levels. d) there would be less energy transferred to the higher trophic levels.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)

Suppose that f : rn → rm and that a ∈ k, where k is a connected subset of rn . suppose further that for each x ∈ k there exists a δx > 0 such that f(x) = f(y) for all y ∈ bδx (x). prove that f is constant on k; that is, f(x) = f(a) for all x ∈ k
