Match the following and select the correct option.
Column 1 (a) Earthworm | Column 2 (i) Pioneer species |
(b) Succession | (ii) Detrivore |
(c) Ecosystem service | (iii) Natality |
(d) Population growth | (iv) Pollination |
Detrivores are heterotrophs that obtain nutrients by consuming detritus or decomposing plant and animal parts as well as faeces. Earthworm is a detrivore.
In succession, pioneer species like lichen, algae, and fungi, as well as other abiotic factors like wind and water start to 'normalize' the habitat.
Pollination is a type of ecosystem service which enhances the service provided by insects/birds through behavioral interaction.
Natality is the crude birth rate or specific birth rate and is the greatest influence on a population's increase.
Thus, the correct answer is option D.
