Consider the following statements related to ecology:1. All the physical, chemical and biological factors that a species needs in order to live and reproduce is called ecological niche.2. The boundary zone between two ecosystems is known as ecotone.3. The forests in the Arctic’s are known as tundra.4. A biome usually has a distinct climate and life forms adapted to that climate. Biome is more extensive and complex than an ecosystem.Which of the above statements are correct?

The term "ecology" was first coined by the German biologist Ernst Haeckel in 1866, who defined it as "the comprehensive science of the relationship of the organism to the environment." Statement 1: TrueNiche is a term for the position of a SPECIES within an ecosystem. The ecological niche describes the ecological role of a species in the ecosystem and the range of conditions necessary for the persistence of the species.Statement 2: TrueAn ecotone is a transition area between two biomes. It is where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems).Statement 3: TrueTundra is a type of biome where the tree GROWTH is hindered by low temperatures and short GROWING seasons.Statement 4: TrueA biome usually has a distinct climate and life forms adapted to that climate. Biome is more extensive and complex than an ecosystem.
