This inorganic fertilizer gives all the nutrients the plant needs to grow which causes the plant to grow more rapidly and produces the fruits and vegetables quickly. Even though this is less time consuming and less costly, it now has toxins within the fruit or vegetable. When the plant has reached maturity, it is vulnerable to predators that eat the “natural” foods. This is when the plants are protected by fenced in areas so animals such as deer, rodents, or anything else that is harmful to the plans. Growers that are not growing organic foods use pesticides and are the only toxic substances released intentionally into our environment to kill living things.
Factory farming defined II. Differences between the two forms of Farming A. Freedom B. Cruelty C. Negative effects on humans D. Cost . CONCLUSION Factory or Natural Farming of Animals? Lately, people are becoming more aware of the necessity to be healthier through prevention by exercising more, but most importantly by following a healthier diet.
Compare JVTF methods (such as crop rotation, pest management, or use of cover crops) with more traditional farming methods that have a negative impact on the environment. . They don’t use pesticides so not a good chance that the food will be tainted. Crop rotation is nice because its makes sure that you have room for your next seasons crops and they also can have sells on the leftover crops from last harvest. 8.
In order for a group of people to even become food producers they had to live in a geographical area that had domestic able plants, as well as a climate that would support their growth. The transition from hunter gatherer to food producer enabled people to become sedentary. Farmers remained near their crops and had more children than hunter gatherers because they weren’t moving around looking for food. This in turn gave rise to the population growth. Food production also led to the storage of food surpluses.
Natural selection stabilises a population, this means that there are selected against extreme variants of a population to bring up a more uniform normal distribution for the population. This shows that natural selection does not increase variation, but it actually decreases variation within a population. For natural selection to be successful there must be a variety to choose from, there must be numerous individuals and those who are more successful in the habitat will be selected to reproduce. Those not adapted to the environment will die. Examples of this can be found in the fossil records.
Each and every species has a significant role. It is this which allows humans, animals and plants to share the planet. If a population is not diverse enough, they will eventually die out, which could cause a domino effect, as many other species may follow too, and biodiversity is what creates stability in our ecosystems. An example given could be a rainforest, if it wasn't diverse, it
Meat from hunts were considered the bigger prize, but they weren’t always successful. When the men came back empty-handed, the people would rely on plant foods gathered from the women. Both did their part to ensure everyone’s survival. But, then a new era started where societies would rely on nurturing plants and animals. This meant no more moving from place to place.
Pesticides are used in a certain amount to help farmers maintain unwanted pests from eating or destroying their crops, and helps preserve the produce life. Doing this helps the economy by maintaining the price of food. Pesticides have their pros and cons. To ensure that pesticides do not contribute more harmful waste than needed is to dispose of pesticides and their containers properly. Purchase pesticides; specific to the pests you are trying to control this way the pesticide does not harm other species in the process.
For photosynthesis to takes place, there should be a presence of chlorophyll, light, 〖CO〗_2 water and suitable temperature. Temperature, light intensity, and carbon dioxide concentration are possible limiting factors on the rate of photosynthesis. It is because if more than one essential condition for chemical process is favorable, its rate will be limited by the factor which is nearest its minimum value. I am going to observe the effect of using different colors of light on the rate of photosynthesis in the experiment. Since I am interested to grow flowers by myself, I have used to grow variety of flowers and plants.
Over long periods of time variations in a species occur in a population, so the later generations are distinct from ancestral ones. In this time a new species may appear. Geographic location and selective pressures also contribute to the formation of a new species. If there is a natural barrier, (mountains, oceans etc) species will begin to adapt to the different environments, thus causing basically a new species such as the Galapagos finches. An important thing to emphasize is that natural selection is the individual while evolution is the population.
