1 Nikimmit CHAPTER 4 ECOLOGY A. Definition of Ec logy. Organisms depend on each other and on their environment. No organism or group of organisms can exist without influencing or being influenced by the environment and by other living things. The study of the relationship between living things and the environment is called ecology. 2.

In their studies of ecology, scientists divide organisms into the following groups: 1. Populations. All organisms of the same kind (all members of the same species) living in a 'certain area make up a population. For example, all the ants living in a particular field make up a population of ants. 2. Communities. All the populations living in the same area make up a community. 3. Ecosystems. A community (all the living things in a particular area) plus the nonliving environment in which the community exists make up an ecosystem. 4. Biosphere. The portion of the earth in which life exists is called the biosphere. The biosphere is made up of many ecosystems. 1. All members of a species living in a certain area make up a ptr i. C. Limiting Factors. Living things need space, water, air, food, light, proper temperature, and a 1% constant supply of energy. If organisms do not (--t4 have enough of any one of these factors, their A.umbers will be limited. These nonliving parts of the environment are called limiting factors because they limit the numbers and kinds of organisms that can exist in an area. For example, the shortage of water and the hot temperatures of the desert determine the kinds of plant and animal life that can survive. Temperature and water supply are limiting factors in a desert environment. 1. Define the term "limiting factor", If elf ht rt't I) ) 64.,\ 4t ( ree limiting factors are and D. Natural Communities. Natural communities may be classified according to the physical characteristics of their environment, such as aquatic (water) or terrestrial (land). Communities are also classified by the dominant (most common) kind of plant life in the area. Plant communities are usually determined by the climate of the area. Table 4 gives the characteristics of the major kinds of plant communities. 14

Over long periods of time, natural communities change from one kind to another. This orderly and predictable change is known as biological succession. As a result of succession, a new kind of community replaces the existing community The new community is quite different from the original community Succession is caused by changes in growing conditions brought about by the existing corn- FIGURE 15.

3 F. Balance in an Ecosystem. The balance in an ecosystem is the result of complex interactions between living things and the environment Within a balanced ecosystem, there is a constant flow of energy and materials between organisms and the environment. 1. Energy Flow. Energy enters an ecosystem when producers (green plants and algae) capture light energy during photosynthesis. Plants use some of the energy for their own life processes, and some energy is stored in food substances produced by the plants. The energy in the food is transferred to consumers (animals) when the plants are eaten. Whenever energy is transferred from one organism to another, some energy is lost. The flow of energy through an ecosystem is in one direction. Energy must constantly be supplied to the ecosystem if organisms are to survive. Energy flow through an ecosystem is represented by food chains and food pyramids (Figure 16). In both food chains and food pyramids, the greatest amount of energy is present at the producer level. web is made up of many food chains, and re resents the path of energy flow, in a communit (Figure 17). HAWK SNAKE -Nue- FROG GREEN PLANTS "C MOUSE FIGURE 17. FOOD WEB. GRASSHOPPER 3. Materials Cycles. In a balanced ecosysterr materials are cycled between the living organ isms and the nonliving environment. Throug these cycles, the same materials are used ow and over again. Materials that are recycled i ecosystems include oxygen, carbon, nitroger and water (Figure 18).

The natural balance in an ecosystem may be disturbed by natural events or by human activity Major natural disturbances include floods, fires, earthquakes, climate changes, and disease. Human activities that disturb the balance of ecosystems include cutting down forests, clearing land, and building dams. These changes may cause erosion, floods, and loss of wildlife. rat1 1.

Some human activities that upset the balance of osystems lude and G. Conservation of Resources. Humans are faced with serious shortages of natural resources. We must learn to conserve (save) our natural resources. Soil, trees, and water are classified as renewable resources. They are replaced by natural processes overtime. Nonrenewable resources, such as minerals and oil, are not replaced by natural processes. Our supplies of these resources will eventually run out, even through some are recycled in the ecosystem. 3. The diagram illustrates a kind of community The kinds of plants that can live in this area are limited by a lack of (1) air (2) minerals (3) animals (4) temperature 4. The community illustrated in the diagram is (1) tundra a taiga (3) tropical rain forest (4) deciduous forest 5. Natural communities change in an orderly and predictable sequence. This process of change is known as (1) migration (2) hibernationesuccession (4) life cycle 17
