What is a resource in ecology?

In ecology, a resource is a substance or factor that is required for an organism to survive, grow, and reproduce. Resources can be divided into two types: abiotic (non-living) resources such as sunlight, water, and nutrients, and biotic (living) resources such as food and habitat. The availability and distribution of resources play a critical role in shaping ecosystems and influencing the interactions between species.

Moving into a population?

Moving into a new population involves establishing yourself within the community, building relationships with local residents, and adapting to the culture and norms of the area. It can be helpful to participate in community events and activities to connect with others and learn more about the community. Building trust and showing respect for the existing population is key to successfully integrating into a new area.

I am a student writing a report about an environmental problem Can you send me information?

The information gathering is up to you, but here are great current topics to discuss:

- Three Gorges Dam in China (massive wetlands destruction = greater flooding and a slew of other problems)

- Aswan High Dam in Egypt (lots of ecological and political problems)

IF you want a general issue, you can consider climate change (kinda overdone), deforestation, or desertification, which is a more recent issue.

Was the tritium leak from the HFBR dangerous?

Yes, the tritium leak from the High Flux Beam Reactor (HFBR) was considered dangerous because tritium is a radioactive isotope that can pose health risks if released into the environment. It can contaminate air, water, and soil, leading to potential health hazards for nearby communities.

A frog does not chew his food What do the positions of its teeth suggest about how the frog uses them?

The positioning of a frog's teeth, which are located on the upper jaw, suggest that they are mainly used for gripping and holding onto prey rather than for chewing. Frogs typically swallow their food whole and rely on powerful jaws and a strong throat muscle to push the food down their throat.

What are 4 Methods scientists use to determine population size in an ecosystem?

  1. direct observation-count
  2. indirect observation-estimate
  3. sampling-count small number in a small area and multiply to get the number in the large area
  4. mark and recapture studies-capture, mark, release

Dr Willard is studying the way in which infant siblings interact with one another in the home According to the ecological approach Dr Willard is studying the children in their?

natural environment, examining how their interactions with each other are influenced by factors such as physical surroundings, family dynamics, and cultural influences. This approach considers how the immediate environment shapes the children's development and behavior within their everyday context.

What are 3 possible outcomes of competitive exclusion?

  1. Extinction of one of the competing species due to the other being more efficient at utilizing resources.
  2. Evolution of one or both species to occupy different ecological niches to reduce competition.
  3. Coexistence through partitioning of resources or establishment of a competitive hierarchy.

People calling for more stewardship generally believe what?

People calling for more stewardship typically believe in taking better care of the environment, resources, and communities by making more responsible and sustainable choices. They advocate for actions that prioritize long-term wellbeing over short-term gains to ensure the health and vitality of our world for future generations.

Difference between intra and inter regional transportation?

international means between two or more countries. Inter-regional means between two or more regions, where a region can be a part of a country (for example, the Pacific North West), or a collection of countries (for example, Northern Europe).

A piece of flat grassland is called as?

Different names in different parts of the world, actually

North America - prairie

South America - pampas

Europe - plain

Africa - veldt (south) and Savannah (central)

Asia - steppe

Explain how symbiotic relationships are similar and different from predator-prey interactions?

different:A symbiotic relationship involves 2 species living together. Mutualism is when both benefit. Commensalism is when one benefits without harming the other. Parasitism is when one species benefits while harming--but not killing--the other. An example of parasitism would be a tick on a dog. If the dog died, it would stop pumping blood for the tick to consume.

In predator-prey relationships, most often one party must die for the other to benefit.

simmilar:

both have at least one species that benefits

Energy flow in an ecosystem is not cyclic because energy is?

lost as heat through metabolism and cannot be recycled back into the system.

What is ecological bubble?

An ecological bubble is a concept where a closed environment is created to mimic an ecosystem, allowing for scientific research or habitat preservation. It aims to sustain a balance of living organisms, resources, and environmental conditions within the contained space. These bubbles can provide insights into how ecosystems function and can also be used for educational purposes.

Function of chitinous teeth of crayfish?

Chitinous teeth in crayfish help them grasp and manipulate food as they feed. These teeth are used to crush and grind food items, making it easier for crayfish to consume their prey. Additionally, chitinous teeth aid in the breakdown of food particles during digestion.

Which of the following is the correct order of the layers of the gastrointestinal tract wall from lumen to external surface?

The correct order of the layers of the gastrointestinal tract wall from lumen to external surface is mucosa, submucosa, muscularis externa, and serosa (or adventitia depending on the location in the body).

How Amway products are eco friendly?

Amway products have been organic, biologically natural and they don't pollute sewage systems and septic tanks. They break down easily. Their containers are recyclable. Their products for the body are of high quality and natural.

What is an example of a community in ecology?

A Biological Community can be a certain area of forest, consisting of trees, smaller plants, fungus and much more. All of these organisms are living together in the same area (habitat), and are interdependent of one another.

Also: one tree, a pond, a beach etc.

Paramecia are heterotrophs explain this statement?

Paramecia are heterotrophs because they obtain their nutrition by ingesting organic matter or other organisms. They do not have the ability to produce their own food through photosynthesis like autotrophs. Instead, they rely on consuming other organisms for energy and nutrients to survive.

Ecological relationship of echinoderms to other organisms?

Echinoderms have various ecological relationships with other organisms. For example, they may have mutualistic relationships with certain species that help them remove parasites, or they may have predatory relationships with smaller organisms that they feed on. Echinoderms also provide habitats for other organisms by creating complex structures on the seafloor.

The size of a food web is limited by the number of what?

The size of a food web is limited by the number of species present in the ecosystem. As more species are added to the web, it becomes more complex and interconnected, which can be constrained by the available resources and ecological interactions within the ecosystem.

What is difference between hydrophyte and mesophyte?

Hydrophytes are plants that grow in water or in very wet soil, adapted to living in aquatic environments, while mesophytes are plants that grow in moderate moisture conditions, neither too wet nor too dry. Hydrophytes have adaptations for living in water, such as floating leaves, while mesophytes have adaptations to conserve water, such as waxy cuticles on their leaves.

Do ecologists use food chains to keep animals from eating certain plants?

No, ecologists use food chains to understand the flow of energy and nutrients in an ecosystem. They do not use food chains to control what animals eat certain plants.

The initial ecological consequences of falling water tables?

Falling water tables can lead to decreased water availability for plants, reduced soil moisture content, and alterations in local hydrological cycles. This can result in lower crop yields, increased competition for water resources, and changes in ecosystem dynamics. Additionally, declining water tables can impact the quality of groundwater, leading to issues such as saltwater intrusion in coastal areas.
