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.
Which water ecosystem has the fewest nutrients?
The water ecosystem with the fewest nutrients is typically the open ocean. Nutrient levels in the open ocean are often low due to reduced mixing of nutrients from the seafloor and limited input from land sources, resulting in low productivity compared to other ecosystems like rivers, lakes, or coastal areas.
How can environmental change affect carrying capacity?
Environmental change can lower carrying capacity by reducing available resources like food and water, increasing competition among species. It can also directly impact the habitat suitability for certain species, making it harder for them to thrive and survive. Overall, environmental change can lead to a decrease in carrying capacity for a given ecosystem or population.
How has human use of salt marshes changed over time?
In the past, salt marshes were often drained for agriculture, land development, and salt production. However, there is now greater recognition of their ecological value for biodiversity, storm protection, and carbon storage. Efforts are being made to restore and protect salt marshes for these critical ecosystem services.
Is a banana a biotic or abiotic factor?
An apple is a biotic factor because it can reproduce with its seeds. Apples go through photosynthesis. It also responds to energy like sunlight. It is made up of cells. Those cells have DNA.
Can most organism survive if they are taken out of there habitat?
It depends on the organism and how different the new environment is from their original habitat. Some organisms may adapt and survive, while others may not be able to survive due to factors like temperature, moisture levels, food availability, or competition with other species.
What are the abiotic factors of a chinchilla?
The abiotic factors that can affect a chinchilla include temperature, humidity, light/dark cycles, ventilation, and noise levels in their environment. Chinchillas are sensitive to high temperatures and require well-ventilated areas to prevent overheating. Proper lighting and noise levels are also important for their well-being.
What affect can pesticides have on organisms that they weren't intended to affect?
Pesticides can unintentionally harm non-target organisms through aerial drift or runoff, disrupting the natural balance of ecosystems. They may also accumulate in the environment, affecting species higher up in the food chain through bioaccumulation. Additionally, some pesticides can persist in the environment for a long time, continuing to impact organisms even after their initial application.
Are saplings examples of pioneer species?
I don't think so because in my science text book it states that mosses and lichens are the first organisms to start growing in an environment again and pioneer species have to be the first species to arrive. After the mosses grow then die decaying matter builds up on them and other plants can grow. Hope this helped :)
What happens if an area becomes over populated with too many of the same species?
Typicaly the species will plateau and the population will reduce as competition for increasingly scarce resources increases. This can (but will not always) lead to extinction in extreme situations, but the most likely outcome is a much lower population and the resulting evolutionary bottleneck.
What is the advantage of studying the environment at the ecosystem level?
Studying the environment at the ecosystem level allows for a more holistic understanding of how different organisms interact with each other and their surroundings. This perspective helps in identifying complex relationships, feedback loops, and potential impacts of human activities on ecosystem health and resilience. It also aids in developing effective conservation and management strategies to maintain ecosystem balance.
What condition do animals that live in freshwater ecosystems have to adapt to?
Animals in freshwater ecosystems have to adapt to changes in water flow, temperature, oxygen levels, and water quality. They also need to adapt to competition with other species for resources and potential predators in their environment. Additionally, they may need to develop specialized physiological mechanisms to regulate salt concentration in their bodies.
How many food chains make up the food wed?
Multiple food chains make up a food web. A food web shows the complex network of interactions between different organisms in an ecosystem, including multiple interconnected food chains. Each organism in a food web can be a part of multiple food chains, showcasing the interconnectivity of an ecosystem.
Can 2 niches overlap the same niche successfully?
Yes, two niches can overlap successfully if they complement each other or offer a unique angle. This overlapping can create a hybrid niche that caters to a broader audience or provides a more comprehensive solution. It's essential to understand the target audience's needs and ensure that the combination adds value and relevance.
What is the intersection of healthy ecosystems healthy economies and healthy communities?
There is an intersection. If there is a healthy ecosystem, a balance is restored amongst all human beings and as a result have healthy communities. If they have healthy communities, that means more work can be done, thus resulting in healthy economies.
What is a bacteria organism that eats dead organism?
Decomposers like certain bacteria, such as Bacillus and Clostridium species, break down dead organisms into simpler compounds to obtain nutrients for growth and reproduction. These bacteria play a crucial role in recycling nutrients and breaking down organic matter in ecosystems.
Do Scorpions like to hide under rocks?
Yes, scorpions are nocturnal creatures that like to hide during the day to avoid predators and conserve energy. Rocks, logs, and debris provide them with secure hiding spots where they can rest undisturbed.
Which stage represents a pioneer community?
The pioneer community stage is the first stage of ecological succession, where the environment is colonized by plants and animals for the first time. This stage is characterized by hardy, fast-growing species that can establish themselves in harsh conditions. Over time, these pioneer species will make way for more complex and diverse species as the ecosystem develops.
Where would an ecologist least likely to go to study primary succession?
A new island formed by volcanic eruption
What intact ecosystems provide for humans?
Intact ecosystems provide numerous benefits for humans, including clean air and water, fertile soil for agriculture, pollination for crop production, and biodiversity that supports food security and medicine discovery. In addition, intact ecosystems offer recreational opportunities, regulate the climate, and help mitigate natural disasters like floods and droughts.
Yes, salmon is a heterotroph because it relies on consuming other organisms for its energy and nutrients rather than producing its own through photosynthesis.
Is it true that logistic growth curves are density-dependent?
Yes, logistic growth curves are density-dependent because they incorporate the concept of carrying capacity, which is the maximum population size that an environment can sustain. As the population size approaches the carrying capacity, the growth rate slows down due to limited resources and increased competition, making it density-dependent.
What can you do if you find an invasive species?
If you find an invasive species, report it to local authorities or organizations that handle invasive species control for proper identification and management. Avoid spreading the species further by not intentionally moving or planting it elsewhere, and consider helping with removal efforts if possible.
What does population mean in a community?
A population in a community means the specific kind of organism (plants and animals)
living in a community (all the living things in an ecosystem)
