Question

PLEASE help with these two needs to be correct or i have to retake it, while mark highest if you are correct thank u :)

1.) Which of the following is an example of a non-extractive resource?

Ecotourism

Fossil fuels

Oysters

Sand


2.) The seafloor holds promise as a source of many natural resources, including valuable metals. As demand for natural marine resources increases, mining these resources from the seafloor also increases. One concern of seafloor mining is the disruption of the seafloor habitat. Which of the following describes the most likely impact of seafloor mining on the surrounding marine environment?

Alteration in seafloor sediments rich in carbon would cause loss of species and an unbalanced population in marine food webs.

Increased levels of metals in the ocean would result in decrease of marine bivalves due to weakened shells.

Methane gas would pollute the marine environment and cause an overabundance of bacteria that feed on it.

Nonrenewable resources in the marine environment would become depleted and affect the balance of the ecosystem.

Answer 1

Ecotourism is when people are encouraged to tour natural environments, often of endangered species, in order to observe wildlife. You see, when people can see the beautiful places in nature that are at risk, they will work to conserve the environments. Transportation through these places uses the land as a resources without taking anything from it. Non-Extractive Resources are pieces of land and places in nature that benefit the economy without people extracting resources or artificially developing things within the ecosystems.

Metals on the ocean floor aren't renewable. They are formed over long periods of time, and the organisms that feed on them will become extinct without it. For example, iron is one of the most heavily mined metals in the ocean, as well as a primary food source for phytoplankton—who are one of the species at the base of the marine food pyramid, meaning they are essential to the survival of other species.

Answers:

1. Ecotourism

2. Alteration in seafloor sediments rich in carbon would cause loss of species and an unbalanced population in marine food webs.

Hope this helps!
