Question

Paragraph nt 31) With the exception of lipids, plants are capable of producing all the organic molecules they need using water and minerals from the soil and energy stored in the sugar molecules they make through photosynthesis. 32) The introduction of invasive species may increase the environmental resistance for a native species. 33) For bacteria living in benthic regions of a lake, exponential growth could continue even if the carrying capacity of the environment was exceeded provided nutrients were unlimited. 34) Major end products from photosynthesis include oxygen gas and simple high energy carbohydrates. 35) As soon as a population achieves the replacement fertility rate of 2.1, the population will stop growing. 36) The biosphere is so large that, unlike the case of the more simple ecosystems, it is impossible to disturb the balances that exist in this ecosystem. 37) Once populations exceed the carrying capacity of the environment, 38) Climax communities generally exhibit the greatest species diversity 39) Chemicals that make up living organisms are constantly recycled between organisms and the Earth. 40) A niche is the location within an environment within which a species lives. T 41) Modern farming practices have advanced to the point where they have little impact on the balance of existing ecosystems in the area. 42) According to the second law of thermodynamics, when energy is converted from one form to another, some of that energy is transformed into heat energy, which is generally released from the "system." 43) The majority of precipitation reaching land is derived from evaporation of oceanic waters 44) A population is comprised of one or more species of organisms that may interact but do not interbreed.
