Plants growing in dry and saline soil are called
1 Xerophyte
2 Hydrophyte
3 Halophyte
4 Heliophyte
Explanation:
Exp: Plants growing in saline soils (high concentration of salts) are halophytes. - Xerophytes are those plants which grow in deserts or in very dry places. - Hydrophytes are those plants that grow in water or in very wet places. - Heliophytes are adapted to live under plenty of sunlight.

The species of plants that play a vital role in controlling the relative abundance of other species in a community are called
1 edge species
2 keystone species
3 pioneer species
4 seral species
Explanation:
Species with disproportionally large effect on its environment relative to its abundance. - A keystone species is a plant and animals that plays a unique and crucial role in the way an ecosystem functions. Without keystone species, the ecosystem would be dramatically different or cease to exist altogether. - This is one of the most fundamental and bidirectional patterns in ecology and displays a consistent general form with many rare species and few abundant species occurring within a community.

Recapitulation theory was proposed by
1 E. Haeckel
2 Mendel
3 Hugo de Vries
4 Von Baer
Explanation:
The recapitulation theory also known as biogenetic law or " ontogeny recapitutlates phylogeny " was proposed by Ernst Haeckel. Ernst Haeckel suggested that during the development of an individual organism (ontogeny), the stages of development recapitulate or mirror the evolutionary history of that species (phylogeny). This theory proposed a connection between embryonic development and evolutionary history

A system of rotating crops with legume or grass pasture to improve soil structure and fertility is called
1 Shifting agriculture
2 Ley farming
3 Contour farming
4 Strip farming
Explanation:
Rotating crops with legume or grass pasture to improve soil fertility is called as lay farming. Ley farming, the growing of grass or legumes in rotating alternating cultivation of grasses or legumes with cereals or tillage, crops as a soil conservation measure
