(choose all that apply) river ocean estuary wetlands 16 multiple choice 2 points the variety of habitats, the species residing in them, and the ecological processes is habitat diversity genetic diversity ecosystem diversity species diversity

Explanation:

1. Burning fossil fuels releases carbon - stored for millions of years as carbon dioxide into the atmosphere. Recycling, solar energy, and tree - planting reduce or sequester carbon dioxide.
2. Oceans and estuaries are marine biomes. Rivers are freshwater biomes and wetlands can be freshwater or saltwater, but are not strictly marine.
3. Ecosystem diversity encompasses the variety of habitats, species within them, and ecological processes. Habitat diversity is about habitats, genetic diversity about genes, and species diversity about species.

Answer:

1. Burning fossil fuels for transportation and energy.
2. ocean, estuary
3. ecosystem diversity
