Primary succession is taking place. Lichens are most often found on exposed rock and are the organisms responsible for initial
Rudik [331]

C

The hygroscopic nature of lichen also does not allow them to survive highly polluted environments. This is because they will also absorb the toxins from the atmosphere into their systems. The toxins will then affect their growth, negatively.

Explanation:

Lichen is one pioneer species in primary succession. They have undefined roots hence do not require soil and can grow on rocks and break them down slowly by chemical weathering (using excreted organic acids). More so lichen does not need to absorb nutrient via roots because the organism is a symbiotic relationship between fungi and algae. The algae can use photosynthesis to manufacture food while the fungi complex hyphae that surround the  algae can absorb water & nutrients from the air due to their high hygroscopic nature.

alex41 [277]

Answer:

r-selected species (e.g., American bullfrog)

Explanation:

The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
