Significantly reduces use of fossil fuels farm machines and transport of crops Makes use of abandoned or unused properties No weather related crop failures Offers the possibility of sustainability for urban centers Converts black and gray water to drinking water Adds energy back to the grid via methane generation Creates new urban employment opportunities Reduces the risk of infection from agents transmitted at the agricultural interface Returns farmland to nature, helping to restore ecosystem functions and services Controls vermin by using restaurant waste for methane generation No-cost restoration of ecosystems: The best reason to consider converting most food production to vertical farming is the promise of restoring ecosystem services and functions This belief stems, in part, from numerous anecdotal observations as to the current biological state of some territories that were once severely damaged either by now-extinct civilizations or over-farming, and, in part, from data derived from National Science Foundation-sponsored long-term ecological research program LTERbegun inon a wide variety of fragmented ecosystems purposely set aside subsequent to an extended period of encroachment The following case studies will serve to illustrate these points.

A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation for example, the large muscles of a weightlifter.

Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment. Also used to describe the process of genetic change within a population, as influenced by natural selection. A graph of the average fitness of a population in relation to the frequencies of genotypes in it.

Peaks on the landscape correspond to genotypic frequencies at which the average fitness is high, valleys to genotypic frequencies at which the average fitness is low.

Also called a fitness surface. A behavior has adaptive logic if it tends to increase the number of offspring that an individual contributes to the next and following generations. If such a behavior is even partly genetically determined, it will tend to become widespread in the population.

Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited -- unless it becomes positively disadvantageous in the new environment.

The diversification, over evolutionary time, of a species or group of species into several different species or subspecies that are typically adapted to different ecological niches for example, Darwin's finches.

The term can also be applied to larger groups of organisms, as in "the adaptive radiation of mammals.

A mode of coping with competition or environmental conditions on an evolutionary time scale. Species adapt when succeeding generations emphasize beneficial characteristics. A person who believes that the existence of a god or creator and the nature of the universe is unknowable.

An umbrella term for various simple organisms that contain chlorophyll and can therefore carry out photosynthesis and live in aquatic habitats and in moist situations on land. The term has no direct taxonomic significance. Algae range from macroscopic seaweeds such as giant kelp, which frequently exceeds 30 m in length, to microscopic filamentous and single-celled forms such as Spirogyra and Chlorella.

One of the alternative forms of a gene. For example, if a gene determines the seed color of peas, one allele of that gene may produce green seeds and another allele produce yellow seeds.

In a diploid cell there are usually two alleles of any one gene one from each parent. Within a population there may be many different alleles of a gene; each has a unique nucleotide sequence.

The relation between the size of an organism and the size of any of its parts. For example, an allometric relation exists between brain size and body size, such that in this case animals with bigger bodies tend to have bigger brains.

Allometric relations can be studied during the growth of a single organism, between different organisms within a species, or between organisms in different species. Speciation that occurs when two or more populations of a species are geographically isolated from one another sufficiently that they do not interbreed.

Living in separate places. The unit molecular building block of proteinswhich are chains of amino acids in a certain sequence. There are 20 main amino acids in the proteins of living things, and the properties of a protein are determined by its particular amino acid sequence.

A series of amino acids, the building blocks of proteinsusually coded for by DNA. Extinct relatives of cephalopods squid, octopi, and chambered nautilusesthese mollusks had coiled shells and are found in the fossil record of the Cretaceous period.

The group of reptiles, birds, and mammals. These all develop through an embryo that is enclosed within a membrane called an amnion.

The amnion surrounds the embryo with a watery substance, and is probably an adaptation for breeding on land. The class of vertebrates that contains the frogs, toads, newts, and salamanders.

The amphibians evolved in the Devonian period about million years ago as the first vertebrates to occupy the land. They have moist scaleless skin which is used to supplement the lungs in gas exchange.

The eggs are soft and vulnerable to drying, therefore reproduction commonly occurs in water. Amphibian larvae are aquatic, and have gills for respiration; they undergo metamorphosis to the adult form.

Most amphibians are found in damp environments and they occur on all continents except Antarctica. Structures in different species that look alike or perform similar functions e.

STUDY: Fossil fuels contribute to ‘petro-masculinity’

Contrast with homologous structures. The recent discovery of deep genetic homologies has brought new interest, new information, and discussion to the classical concepts of analogous and homologous structures.

Homology that evolved before the common ancestor of a set of speciesand which is present in other species outside that set of species.As the world population grows, we have a pressing need to eat better and farm better, and those of us trying to figure out how to do those things have pointed at lots of different foods as.

The million-year-old fossil of a nodosaur preserves the animal’s armor, skin, and what may have been its final meal. noun. the faculty of conscious and especially of deliberate action; the power of control the mind has over its own actions: the freedom of the will. power of choosing one's own actions: to have a strong or a weak will.

Diagnostic characters. Ammonites (subclass Ammonoidea) can be distinguished by their septa, the dividing walls that separate the chambers in the phragmocone, by the nature of their sutures where the septa joint the outer shell wall, and in general by their siphuncles..

Sep 06,  · The sun is the ultimate source of energy for our planet. Its energy is found in fossil fuels as well as all living things. Harnessing its energy holds great promise for the world’s energy needs, and it will be heavily called upon as fossil fuels are depleted.
