Do decomposers return raw materials to the environment true or false?
yes the do, they break down large molecules from dead organisms into smaller ones and return important materials to the environment.

What are two different niches in a savanna habitat?
one niche is that lions eat zebras and zebras eat grass OR zebras drink water; a niche is like a role in a play; its the animals role in the eco system
Heat is considered abiotic because it is a physical factor of the environment and not associated with living organisms. It is a form of energy that can affect biotic organisms but is not considered a living component of an ecosystem.
How do earth systems interact in the carbon cycle?
They provide materials organisms need to build their bodies.
What impact if any would an algal bloom be likely to have on its local ecosystem?
If there is a massive bloom, then the algae may cover the whole of the surface of the water, in which case it can block out sunlight for other plants and creatures living below the surface. Other plants cannot perform photosynthesis, and therefore fish can feed onm the plants, and gradually a whole eco system can be destroyed. On the other hand, fish or animals that eat the algae can thrive, and the whole ecosystem can thrive as a result. It depends on what else is in the pond really
What are difference and similarities between communities and ecosystem?
Communities are groups of interacting populations of different species in a specific area, while ecosystems include both the living and non-living components of a specific area interacting with each other. Both communities and ecosystems involve different organisms coexisting and interacting with each other, but ecosystems also include the physical environment as a crucial component.
How do you reduce niche overlap?
To reduce niche overlap, you can differentiate your products or services by focusing on a specific target audience, offering unique features or benefits, and emphasizing your brand's distinct value proposition. Conduct market research to understand competitors and consumer needs better, then position your brand accordingly to carve out a unique niche in the market.
When limiting factors are not ideal, the population may face increased competition for resources, reduced reproductive rates, lower survival rates, and ultimately decline in numbers. This can lead to stress, decrease in genetic diversity, and potential extinction if the conditions persist.
What would happen to the other organisms if all the plants in this ecosystem died?
If all the plants in an ecosystem died, it would disrupt the entire food chain. Herbivores, which rely on plants for food, would struggle to find nourishment, leading to starvation. Carnivores that prey on herbivores would also be affected due to a lack of food availability. This imbalance could result in a mass die-off of many organisms in the ecosystem.
Is wind speed and direction biotic or abiotic?
Wind speed and direction are considered abiotic factors because they are part of the non-living components of an ecosystem. Biotic factors, on the other hand, include living organisms such as plants and animals.
What would happen to the ecosystem if one of the organism increase or decrease?
there well be no animal on earth
Why does an ecosystem need to be stable?
The stability of an ecosystem implies that the ecosystem can survive over time.
From ETAP, below, ecosystems maintain stability by:
- Disposing of waste and replenish nutrients by recycling all elements.
- Using sunlight as their source of energy.
- Maintaining the consumer population such that overgrazing and other forms of overuse to not occur.
- Maintaining biodiversity.
That description fits the definition of a population. It refers to a group of individuals of the same species living in a specific geographic area and interacting with each other, including breeding within the group.
What is the niche of a petrel?
Petrels are seabirds that occupy a niche as highly skilled oceanic foragers, feeding on fish, squid, and other marine organisms. They are often found far from shore, taking advantage of their ability to fly long distances over open water to locate food sources. Petrels play a crucial role in marine ecosystems by helping to regulate populations of prey species.
The process is called forest regeneration. It involves the natural regrowth of vegetation in an area that has been previously disturbed or destroyed, eventually leading to the re-establishment of a diverse ecosystem similar to the original. This process is crucial for restoring biodiversity and ecosystem services in forests.
Wool is biotic. It is the hair of a sheep (or sometimes other animal).
What non living factors effect carrying capacity in a lake?
Non-living factors that can affect carrying capacity in a lake include nutrient availability (such as phosphorus and nitrogen levels), water temperature, oxygen concentration, and the physical structure of the lake (such as depth and shoreline complexity). These factors can influence the availability of resources for organisms and thus impact the population size a lake can support.
Are ponds and lakes flowing water ecosystems?
Living- Fish, plants, bacteria, and things like that
Non-living- rocks, water, waste, and other things like that.
What happens when an organism dies in an area with low oxygen?
When an organism dies in an area with low oxygen, the decomposition process slows down because bacteria and other decomposers that rely on oxygen for energy are less active. This can result in slower breakdown of the organic matter and preservation of the remains for longer periods of time.
What will happen if carrying capacity of a habitat is reached?
If a field can sustain ten sheep, and the farmer puts twenty sheep in the field, overgrazing and starvation will quickly ensue. So a habitat that becomes overcrowded could fail and, in extreme cases, turn to desert.
Where is your ecosystem located?
is the community of organisms in an area and the physical factors with which they interact
Why do you see fewer and fewer animals at each higher trophic level?
Animals at higher trophic levels have less energy available to pass on to the next level due to energy loss through metabolism, movement, and waste. This leads to a decrease in the number of animals at each successive trophic level as energy is inefficiently transferred up the food chain.
