The connection between plant productivity and biodiversity is a significant topic in ecology, although it has been controversial for decades. Both productivity and species diversity are constricted by other variables such as climate, ecosystem type, and land use intensity. [ 24 ]
The industry provided 500 permanent jobs and seasonal work for 2,500 Nova Scotia workers. [10] Between the 1996 and 2001 Census of Agriculture the total area devoted to Christmas tree production in Nova Scotia fell 18.1 percent to 23,450 acres (94.9 km 2). [11] Production was spread out over 535 farms, one-third less than in 1996.
Specialise in agricultural productivity. They study commercial plants, animals and cultivation techniques in order to improve the productivity and sustainability of farms and agricultural industries [10] and [11] Agricultural scientists have a higher-than-average proportion of full-time jobs and earnings are above average.
Hemp and wool from sheep are the main areas of fibre production of Canada. Wool production was on average 16,022,000 pounds (7,267 t) in the 1930s and 9,835,000 pounds (4,461 t) in 1949.. [41] Fibre flax from flaxseed has been exported to the United Kingdom. Crop growers may supplement their income with beeswax and honey and learn beekeeping.
For example, the sun releases 10,000 J of energy, then plants take only 100 J of energy from sunlight (exception- Only 1% of energy is taken up by plants from sun); thereafter, a deer would take 10 J (10% of energy) from the plant. A wolf eating the deer would only take 1 J (10% of energy from deer).
A tropical plant community on Diego Garcia Rangeland monitoring using Parker 3-step Method, Okanagan Washington 2002. Plant ecology is a subdiscipline of ecology that studies the distribution and abundance of plants, the effects of environmental factors upon the abundance of plants, and the interactions among plants and between plants and other organisms.

Theoretical production ecology is the quantitative study of the growth of crops. The plant is treated as a kind of biological factory, which processes light, carbon dioxide, water, and nutrients into harvestable products. The main parameters are temperature, sunlight, standing crop biomass, plant production distribution, and nutrient and water ...
Ecosystem services are ecologically mediated functional processes essential to sustaining healthy human societies. [6] Water provision and filtration, production of biomass in forestry, agriculture, and fisheries, and removal of greenhouse gases such as carbon dioxide (CO 2) from the atmosphere are examples of ecosystem services essential to public health and economic opportunity.
