Answer:
d.Primary Succession
Explanation:
ECOLOGICAL SUCCESSION is the series of changes that a particular ecosystem undergoes over a particular period of time. Ecological succession can be of two types viz: primary succession and secondary succession.
Primary succession is a type of ecological succession that involves the colonization of a barren area of land with no soil i.e. no pre-existing organisms. The barren area consists of bare rocks and surfaces that are colonized by organisms like LICHENS for the first time. These organisms are called PIONEER.
The lichens act on the bare rocks by secreting chemicals that help degrade the rock particles to form soil, which paves way for other organisms like plants to grow.
Answer:
B. Osmosis
Explanation:
Osmosis is the process in which oxygen and carbon dioxide exchanged occur between the alveoli and the capillaries because the oxygen enters the body and the carbondioxide gas leaves the cell through a semi-permeable membrane and we know that Osmosis is a process in which smaller molecules moves from higher concentration to lower concentration through semi-permeable membrane of the cell.
