Explanation:
Green algae are present in the most diverse environments. The vast majority of species, approximately 90%, are freshwater, with a cosmopolitan distribution, that is, they have a wide distribution on the planet. It is the predominant group of freshwater plankton. BASIC CHARACTERISTICS: Eukaryotic, Chlorophyll a and b, Xanthophylls (mainly lutein) and Carotenes (mainly β-carotene), Reserve: starch, Cell wall: mainly cellulose, Presence of flagella at some stage of the life cycle.
Red algae: Cell wall - consists basically of two parts, one internal and rigid, formed by cellulose microfibrils (most red algae), and the other outer, mucilaginous, formed by galactan polymers, such as agar and carrageenans. Certain groups of red algae have calcium carbonate deposition on the wall, giving the stalk great rigidity. This deposition may be in the form of aragonite or calcite. BASIC CHARACTERISTICS: Eukaryotic, Chlorophyll a and Phycobiliproteins (b, re-phycoerythrin, allophycocyanin and echo-cytocyanin), Xanthophylls (zeaxanthin, lutein, etc.) and carotenes (mainly β-carotene), Reserve: Cellular starch: cellulose, agar and carrageenan, Absence of flagella at all stages of life, including gametes and spores.
Answer:
b. The number of cactus plants would increase.
Explanation:
Food chain is defined as a linear netwrok between producer and high level predators of environment and shows the flow of energy between them.
Kangaroo rats are rodents which lives in desert and feed over cactus plants, grass and other isects for their survival. If kangaroo rats will be removed from the food chain, the number of cactus plants will increase as kangaroo rats will not be there to feed them and number of snakes will decrease as snakes may die as they feed over kangaroo rats.
Hence, the correct option is b.
