March 2026 THREATS TO MOSS HABITATS As with many plants and animals, habitats of mosses are being destroyed due to human activities or environmental changes. Habitat destruction of mosses occurs through deforestation, urban development, or by agriculture. Increasing global temperatures alter the moisture levels and the rising temperatures destroy habitats where moss could flourish in the past. The sexual reproduction of mosses can also be disturbed. 2.1.1. Name the kingdom to which moss plant belong. 2.1.2 From the extract, give TWO main causes of habitat déstruction of moss. 2.1.3.

Life Scignces jownloaded from Stanmomephysics.com 3.3 Group of researchers conducted an investigation to determine the effect of cephalisation on survival chances of aquatic animals. The procedure was as follows: 50 male jellyfish and 50 male catfish were collected from the Indian ocean. Both species of fish were kept in the same lake with predators for the period of 4 months. e The number of all fish present in the lake were counted from Jan to Apr. In total, 64 fish were collected in April and 47 were catfish and 17 were jellyfish. NOTE: Jellyfish belong to Phylum Cnidaria 3.3.1 3.3.2 3.3.3 3.3.4 3.3.5 : Catfish belong to Phylum Chordata The results are shown in the line graph below.
