Ecosystems

Three factors that determine which types of plants are common to a place are climate (temperature and precipitation), soil type (composition, pH, and drainage), and topography (elevation, slope, and aspect). These factors influence the availability of nutrients, water, and sunlight, as well as the ability of plants to survive and thrive in a particular environment.

Access to water is a critical factor in determining where Australians choose to live. People tend to prefer living in areas with reliable water sources for drinking, agriculture, and recreation. Regions with limited water availability may have lower population growth due to challenges in meeting basic needs and sustaining economic activities. Overall, access to water influences the livability and desirability of different locations in Australia.

A food web is a diagram that shows how energy in food flows from one organism to another in an ecosystem. It depicts the transfer of energy through various trophic levels, from producers to consumers and decomposers. Each organism is shown within the web based on its feeding relationships with other organisms.

Climax communities are considered stable and generally do not undergo succession unless there is a major disturbance, such as a wildfire or human intervention. These disturbances can disrupt the climax community, leading to a new round of succession and potentially changing the composition of species in the ecosystem.

Living things exhibit characteristics such as growth, reproduction, response to stimuli, metabolism, and organization that distinguish them from non-living things. Non-living things lack these characteristics and do not require energy to maintain their structure.

Resource competition among plant species can lead to niche differentiation, where plants partition resources such as sunlight, water, and nutrients to reduce competition. This can result in the coexistence of species with different resource requirements within the same habitat. Conversely, intense resource competition can also lead to competitive exclusion, where one species outcompetes others and dominates the area, leading to a loss of biodiversity.

Commensalism is similar to parasitism, except the host doesn't get hurt. Examples of this are mites which feed on the wasted parts of the body of an animal like skin flakes and hair, not hurting the host, but doesn't benefit the host either.

Yes poor reproductive succes does lead to extinction most of the time. for example the whooping crane reproduces very slowly. The first fledging to emerge from its egg kills its brother or sister. Less animals, slow reproduction. If there were ever accidents or if the animal died, and they never had babies, the more and more often that this happens the more likely that animal is to eventually become extinct.

This is impossible, because the producers are all plants and 'suddenly' does not happen when you are talking evolution. Hypothetically, the population would decrease relative to the number of producers that became consumers. By switching sides they would increase the number of consumers and decrease the number of producers, meaning there was not enough food to go around and many consumers would starve.

Rice is a primary producer, so it is considered a trophic level 1 organism. It converts sunlight into energy through photosynthesis.

Temperature, time, and pH are the main factors that affect gelatinization. Higher temperatures and longer cooking times generally increase the extent of gelatinization, while pH levels outside the optimal range can inhibit the process. Additionally, the type and concentration of starch in the food product can also influence gelatinization.

Marshes are wetlands typically found near rivers, lakes, or coastlines. They are characterized by shallow water, soft, waterlogged soil, and a variety of emergent vegetation like reeds and grasses. Marshes are important habitats for diverse wildlife such as birds, amphibians, and insects.

No, caves are not considered a type of island ecosystem according to the theory of island biogeography. The theory focuses on the principles that govern the biodiversity and species composition on actual islands, rather than on enclosed, subterranean cave environments.

The non-living components of an ecosystem are called abiotic factors. These include elements such as sunlight, water, temperature, soil, and air. Abiotic factors play a crucial role in shaping the conditions within an ecosystem that influence the living organisms present.

The term is "polyp". Polyps can be classified as either sessile (without a stalk) or pedunculated (with a stalk) growths.

Ferns are biotic organisms because they are living plants that require certain environmental conditions to survive, such as water, sunlight, and nutrients. Abiotic factors, on the other hand, are non-living components of an ecosystem, like temperature and sunlight.

Living organisms are made up of cells that have specific structures and functions, such as a nucleus and organelles. They are also capable of growth, reproduction, response to stimuli, and metabolism. Non-living things do not possess these characteristics and are typically made up of simple molecules or structures without the ability to sustain life processes.

The environment in any community is composed of all the non-living and living things that are naturally on earth. They include forests, rivers, lakes, mountains and rocks just but to mention a few.

Decreasing as human induced Global Warming ravages the Earth.

An example of a self-limiting control is a thermostat on a heater. When the room temperature reaches the desired level set on the thermostat, the heater automatically turns off to prevent overheating. The control function is built in to limit its own operation once the desired outcome is achieved.

A single ecosystem includes all living organisms (plants, animals, microorganisms) and their physical environment (soil, air, water) interacting in a specific area. These interactions create a balance where nutrients and energy flow through the system, supporting the life within it. Each ecosystem is unique due to variations in climate, geography, and species composition.

A form of population growth in which the rate of growth is related to the number of individuals present. Increase is slow when numbers are low but rises sharply as numbers increase. If population number is plotted against time on a graph a characteristic J-shaped curve results (see graph). In animal and plant populations, such factors as overcrowding, lack of nutrients, and disease limit population increase beyond a certain point and the J-shaped exponential curve tails off giving an S-shaped (sigmoid) curve.

occurs when the growth rate of a mathematical function is proportional to the function's current value.

No, succession can also be caused by human activities such as deforestation, agriculture, or urban development. These activities can disrupt the natural processes of succession and result in changes to the ecosystem.

The ecological pyramid is basically the food chain. So, the producers (plants) are at the bottom, then herbivores (plant eaters), then above them are the omnivores or carnivores, and then the most powerful and top of the food chain animals are at the top of the pyramid.
