True because somatic stem cells can be any cell in the body.
"The notion of ecological niche is central to ecological biogeography, which focuses on spatial patterns of ecological communities."Species distributions and their dynamics over time result from properties of the species, environmental variation..., and interactions between the two — in particular the abilities of some species, especially our own, to modify their environments and alter the range dynamics of many other species." Alteration of an ecological niche by its inhabitants is the topic of niche construction. The majority of species exist in a standard ecological niche, sharing behaviors and adaptations similar to the other closely related species within the same broad taxonomic class, but there are exceptions. A premier example of a non-standard niche filling species is the flightless, ground-dwelling kiwi bird of New Zealand, which feeds on worms and other ground creatures, and lives its life in a mammal-like niche. Island biogeography can help explain island species and associated unfilled niches."
An 1815 volcanic eruption in Indonesia was followed by a three-year famine around the world. This was due to:
a.The eruption's ash and gas significantly dimmed the sun.
The volcanic ash and gases like the sulphur dioxde remained suspended in the atmosphere for years. This reduced the availability of sunlight and hindered the process of photosynthesis that the crops perform for their growth. This lead to the death of farm crops causing a global shortage of food production (famines).
e.The eruption contributed to global warming.
The volcanic gases like CO, CO2 and CH4 caused the warming up of earth in the later years. This changed the weather patterns in various parts of the planet leading to drought, floods and cyclones. Such drastic climatic changes harm the crops and lead to their shortage.
As the number of daylight hours increase plant reproduction increase because the light is reflecting on the plant and the plant is opening up<span />
