Ecosystems

This category is a discussion of the environment in which animals, plants, and microorganisms live, how they interact with each other and what the impact of various living entities have on the environment can be found in this section.

What other factors affect how a person will vote?

Some other factors that can affect how a person will vote include their political ideology, level of education, income level, race/ethnicity, and regional influences. Personal values, family background, religious beliefs, and individual candidate characteristics can also play a role in shaping a person's voting behavior. Additionally, media exposure, social networks, and campaign messaging can influence voter decisions.

What trophic level represents the largest biomassin this ecosystem?

The producers, which are usually plants, represent the largest biomass in an ecosystem. They convert sunlight into energy through photosynthesis, providing food for consumers at higher trophic levels.

Is wool an abiotic or biotic factor?

Wool is abiotic, meaning it is a non-living component of an ecosystem. Although it is derived from animals, specifically sheep, it does not possess the characteristics of biotic factors such as growth, metabolism, or interacting between organisms. Therefore, wool is not considered a biotic factor.

What do wind humidity and rocks have in common when it comes to terrestrial ecosystems?

Wind, humidity, and rocks all play important roles in shaping terrestrial ecosystems. Wind can disperse seeds, pollens, and nutrients, while humidity influences plant growth and soil moisture levels. Rocks provide habitats for various organisms and influence soil composition and nutrient availability. Together, these elements contribute to the overall structure and functioning of terrestrial ecosystems.

What provides energy for an ecosytem and all ecosytems on earth?

The sun provides energy for all ecosystems on Earth through photosynthesis. Plants and algae use sunlight to convert carbon dioxide and water into glucose, which is then used as energy by other organisms through the food chain.

If humans remove carnivorous predators from an ecosystem what will probably be the first observable result?

The population of prey species may increase due to reduced predation pressure. This could lead to changes in vegetation, as increased grazing from prey species could impact plant communities. Additionally, there may be a decrease in species diversity as the predator is no longer controlling prey populations.

What are some limiting factors of toucan?

Some limiting factors for toucans include deforestation, which reduces their natural habitat and food sources, as well as illegal pet trade, hunting, and pollution. Climate change can also impact their habitat and food availability, making it more challenging for toucans to survive in the wild.

Are fish abiotic or biotic?

Water lilies are usually biotic, some are abiotic, but most are biotic

Why does a tick suck blood from leeches?

Ticks do not suck blood from leeches. Leeches are blood-sucking parasites themselves, while ticks feed on the blood of mammals, birds, and sometimes reptiles. They have different feeding behaviors and habitats.

What restricts the number of individual organism that can live in an ecosystem?

Factors such as food availability, competition for resources, predation, disease, and habitat space can restrict the number of individual organisms that can live in an ecosystem. These factors determine the carrying capacity of the ecosystem, which is the maximum population size that the environment can sustain over time.

In any ecosystem the basic resources that organisms need for survival are always in limited supply. is a potential result of these limitations?

Competition among organisms for limited resources can arise, leading to natural selection and the development of adaptations that improve an organism's ability to access those resources. This competition can also drive species to occupy different niches within the ecosystem to reduce direct competition.

What is esuary?

An estuary is a partially enclosed coastal body of water where fresh water from rivers and streams mixes with salt water from the ocean. Estuaries are typically brackish in nature and provide vital habitats for various marine and terrestrial species. They also serve as important locations for nutrient cycling and sediment accumulation.

Is there such thing as a cowfish?

Yes, a cowfish is a type of fish that belongs to the family Ostraciidae. They are known for their unique box-like shape and horn-like appendages on their heads. Cowfish are often found in tropical and subtropical waters around the world.

How is energy lost between trophic levels where does this energy ultimately go?

The energy lost between trophic levels is used to keep the organisms in that level alive. For example a rabbit eats some grass. It then has to spend energy to do everything from breathing to moving. It has to expend energy to keep its body temperature high, etc etc. A rabbit who has run around the world 500 times wouldn't provide any more energy to a wolf than one who had sat still its whole life, but it would have eaten far more grass.

Why does food chain triangle shape?

Not sure if you are asking about the food chain, or the food pyramid, so I'll answer both:

The higher you are on the food chain (near the top of the pyramid), the less likely you are to be eaten. Plants are at the bottom of the food chain, because almost everything eats plant matter, however very few plants eat meat! Animals are higher on the chain, and humans are near the top. Just remember, animals will eat humans too, but we are typically smarter so we can out gun an animal.

The higher you go on the food pyramid, the less servings you are supposed to eat. Breads and cereals are at the bottom, which means we are supposed to eat more servings of them than say, meat.

Can you show me a worksheet called food chains and webs that is also called name that critter?

I'm unable to display images or specific files. However, you can create a worksheet named "Food Chains and Webs," which is also known as "Name that Critter," by listing different organisms in an ecosystem and asking students to identify their roles in the food web. Include questions that prompt students to think about the interdependence of organisms in the ecosystem.

Are diverse ecosystems more stable?

Yes, diverse ecosystems are generally more stable because they are better able to withstand disturbances or changes. This is because different species have varying responses to environmental changes, reducing the overall impact on the ecosystem as a whole. In contrast, ecosystems with low diversity are more vulnerable to collapse if a single species is threatened or removed.

What are some disadvantages of broad niche?

There is not a lot of biodiversity; so there are large populations but little variety amongst the environment.

Is water Lily's biotic or abiotic?

Water lilies are usually biotic, some are abiotic, but most are biotic

Is a tree bark abiotic or biotic?

Biotic, anything derived from something biotic or something that was once biotic is too considered biotic.
