With specific examples, How has environmental Factors has influenced the past and present distribution of plants and animals?
Answers
Explanation:
Outline the factors that affect the distribution of plant species including temperature, water, light, soil pH, salinity, and mineral nutrients. High temperature denatures enzymes and retards growth of plants; the rate of transpiration (loss of :water) is also increased
Plant growth and geographic distribution are greatly affected by the environment. If any environmental factor is less than ideal, it limits a plant's growth and/or distribution. For example, only plants adapted to limited amounts of water can live in deserts.
Either directly or indirectly, most plant problems are caused by environmental stress. In some cases, poor environmental conditions (e.g., too little water) damage a plant directly. In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack.
Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. It is important to understand how these factors affect plant growth and development. With a basic understanding of these factors, you may be able to manipulate plants to meet your needs, whether for increased leaf, flower, or fruit production. By recognizing the roles of these factors, you also will be better able to diagnose plant problems caused by environmental stress.
