That should make it more clear . Its the same thing . Both seta and cheta or chaete means bristles. I think the term can be used interchangeably.
The right answer is Lichen.
In ecology, a pioneer species is one of the first forms of life that colonize or recolonize a given ecological area.
Lichens are composite organisms resulting from a symbiosis between at least one heterotrophic fungus called mycobionte, representing 90% of all, and microscopic cells with chlorophyll (green algae or cyanobacteria autotrophic for carbon) called "photobionts" .

Moreover, the biogeochemical cycles move through mainly the biotic and abiotic components of the earth<span>, more elaborately the spheres -biospheres, lithosphere, hydrosphere and atmosphere regions of the ecosystem. These biogeochemical cycles, from its terminology and discernable word morphology- involves the biological, geological and chemical components that make out to complete an exact and purposed cycle. The purpose in these cycles are to maintain balance and to ensure the ongoing process of the living and non-living organisms in the environment. These cycles’ help to living organisms survive and thrive. One popular example is the water cycle. </span>
Coral ecosystems are a source of food for millions; protect coastlines from storms and erosion; provide habitat, spawning and nursery grounds for economically important fish species.
Answer:
d. K+ and Na+ both diffuse into the cell along their concentration gradients and drive the transport of glucose.
Explanation:
Na/K pump is a pump located on the plasma membrane which uses ATP to move 3 Na ions out the cell and brings in 2 K ions into the cell. It is an example of primary active transport. As a consequence,concentration of Na is higher outside the cell, while K concentration is higher inside the cell.
Glucose is transported in the cell against its gradient, together with Na ions (symport) which move down their concentration gradient.
This is an example of secondary active transport because it uses the energy from the primary active transport to move other substances such as glucose against their own gradients.
