An ecosystem engineer can cause a cascade of effects including abiotic and biotic changes. O True
False

O True

Explanation:

Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.

b. small-scale ocean processes

Autonomous underwater explorers will collect information about ocean. These are oceanographers who study local and small scale processes. They study the oceanic phenomena in detail. They gather information on small scale circulation, such as coastal river circulation, dynamics of planktonic communities, sewage outlets that effect the water of the ocean, and oil spill expansion in oceanic water.
