Question

1 multiple choice 4 points which of the following is a potential solution to address hypoxia in aquatic ecosystems? reducing nutrient runoff and pollution increasing nutrient inputs encouraging algal blooms removing aquatic plants 2 multiple choice 4 points which factor is not considered when calculating the ecological footprint of a population? water usage energy consumption air pollution historical population trends 3 multiple choice 4 points what is the primary goal of invasive species management efforts? to control and minimize the impact of invasive species on ecosystems and economies to eradicate all native species to encourage the spread of invasive species to increase biodiversity

Explanation:

1. Hypoxia in aquatic ecosystems is often caused by excessive nutrient runoff (leading to algal blooms which deplete oxygen). Reducing nutrient runoff helps address this.
2. Ecological footprint measures resource consumption (water, energy) and waste (like air pollution). Historical population trends are not part of its calculation.
3. Invasive species management aims to control their impact on ecosystems and economies. Eradicating native species, encouraging invasive spread, or just increasing biodiversity (without addressing invasives' harm) are not primary goals.

Answer:

1. Reducing nutrient runoff and pollution
2. Historical population trends
3. To control and minimize the impact of invasive species on ecosystems and economies
