Fungi serve an important role in the ecosystem as decomposers. Succulent plants like cacti have spines which are modified leaves that conserve water by preventing water loss during the day and collecting condensed water vapor at night. The living creatures in a habitat affect the nonliving elements within the community. The hares consume grasses, then the red foxes predate the hares. How are living things involved in an ecosystem? Science, 28.10. . . Thus, an ecosystem consists of abiotic components comprising physical factors like soil, minerals temperature, rainfall, wind, etc., and biotic components comprising living organisms. 2 How does the living biotic components of an ecosystem affect the non-living abiotic components? For example, abiotic factors like wind and water can aid in the dispersal of pollen and seeds, helping plants reproduce. An ecosystem can be large or small depending upon the . biological community composed of all living organisms and their interactions with the physical environment.

What percentage of the population are creative? All living things depend on their environment to supply them with what they need, including food, water, and shelter. For example, some flowering plants adapt by producing pigment that gives them a bright color which is attractive to some pollinators, like hummingbirds. What is the formula for calculating solute potential? 4 How do organisms interact and depend on each other and their environment for survival? Plants in high-salinity environments also have internal mechanisms to remove the salt. For example, succulents have thorns that protect them from herbivores, while camels have thick, leathery mouths that allow them to feed on thorny plants. Competition is when organisms compete for resources, such as food and territory. Abiotic factors, like sunlight, temperature, water, soil, and air, are interrelated with biotic factors. 8.11(A) Investigate how organisms and populations in an ecosystem depend on and may compete for biotic factors such as food and abiotic factors such as quantity of light, water, range of temperatures, or soil composition.
