Ecosystems

1. Burning of fossil fuels to power industry, transport and to generate electricity.
2. Deforestation: cutting down forests all over the world for firewood and paper-making.

Some natural resources are unsustainable. Once they are gone they are gone forever (such as fossil fuel). They cannot be renewed. They must be conserved (rationed). Others are renewable such as trees and wildlife. These also must be rationed as their numbers are subject to overuse and need time to replenish. The American Indian knew how to manage the natural resources. Bison were hunted out of necessity, not greed. Then the white man came and slaughtered Bison for the fun of it since the Bison sustained the Indians. And the white man killed Bison by the thousands for only one small piece of anatomy leaving the rest to rot in the sun. This is called raping the natural resources, and is criminal. The white man has since come a long way in their primitive evolution as a people. Now the white man enacts state and federal laws to protect many natural resources from overuse and abuse. However some states are way behind still in the evolutionary process and still permit unlimited killing of animals such as the cougar. Texas is one such state siding with rancher special interests who oppose the cougar's right to life.

Factors that can affect a service user's ability to make decisions and be independent include their cognitive abilities, level of support and assistance available, physical and mental health conditions, past experiences, and access to resources and information. It's crucial to consider these factors and provide tailored support to empower service users to make informed choices and foster independence.

An ecosystem is a distinctive area that consists of living and non-living things that interact with each other in their environment. Ecosystems can range in size from small to large and can include various forms of life like plants, animals, and microorganisms.

The drip tip plant has evolved its elongated, downward-pointing leaf tips to efficiently shed excess rainwater in tropical forests, helping prevent fungal growth and allowing more light to reach the lower leaves. This adaptation promotes the plant's overall health and survival in its wet and humid environment.

The niche of an omnivore is to consume a diet that includes both plant and animal matter. This allows them to adapt to a wide range of environments and food sources, giving them flexibility in finding nutrients for survival and reproduction. Omnivores play a critical role in ecosystems by helping to control the population of both plant and animal species.

The carrying capacity of a river refers to the maximum amount of sediment or material that the river can transport downstream. It is influenced by factors such as the river's flow rate, sediment load, and channel characteristics. Exceeding the carrying capacity can result in erosion or sediment deposition, impacting river ecosystems and infrastructure.

Temperate grasslands are called the "granaries of the world" because they have rich, fertile soil that is well-suited for farming. These regions receive enough rainfall to support agriculture but not so much that it leads to excessive moisture or erosion. As a result, temperate grasslands are ideal for growing crops like wheat, corn, and barley, making them important food-producing areas globally.

I assume you mean the energy flow diagram. The sun should be present.

EDIT: Sorry, food web, I remember now. Its strictly a transfer of material. The sun does not transfer any material to plants, and so is not present in food webs.

I expect the main disadvantage would be in holding sediment in place so that estuaries silt up and fill in more quickly than they otherwise would. They will change the ecosystem from tidal flats that flush themselves of toxins with each outgoing tide or with river currents to first a slow moving swamp and finally solid land as more and more sediment and drifting material catches in the roots and soil builds up on top. This is not necessarily a disadvantage but it can be inconvenient to people who fish the estuaries or want to travel by boat as it becomes more and more congested. The change will affect distribution of plants and animals (eg crab/fish types) in the environment too.

Humans are considered stewards of the Earth because they have the ability to positively impact the environment through responsible decision-making and sustainable practices. As caretakers of the planet, humans have a responsibility to ensure the well-being of the Earth and its ecosystems for current and future generations.

Computer modeling can help an ecologist studying a forest ecosystem by allowing them to simulate complex interactions within the ecosystem, predict how it might respond to different environmental changes or disturbances, and test various management strategies without conducting expensive or time-consuming field experiments. It can also help identify key drivers of ecosystem dynamics and inform decision-making for conservation and sustainable management practices.

Yes, organisms can be dispersed by other living things. For example, birds can disperse seeds when they eat fruits and later deposit the seeds in new locations through their droppings. Another example is how burrs or seeds can get attached to the fur of animals and be carried to new areas.

Secondary blepharospasm is usually caused by underlying conditions such as brain injury, neurological disorders (e.g., Parkinson's disease), or certain medications. It can also be a side effect of conditions affecting the eye, such as dry eye or allergic reactions. It is important to identify and treat the underlying cause to alleviate the symptoms of secondary blepharospasm.

An ecological niche is where the animal or plant lives and what it does. It's the "profession" or "job" of the animal or plant. For example, oak trees live in oak woodlands; that's common sense. The oak woodland is the habitat. So if Odium was writing a letter to an oak tree he would address the letter to: Sir Deciduous Oak Tree,

The Oak Forest,

England,

UK What do oak trees do? If you can answer that question you know the oak trees "profession" or its ecological niche. Perhaps you think that oak trees just stand there looking pretty and not doing very much, but think about it. *

A chameleon's limiting factor could be its ability to regulate body temperature, as they are ectothermic and rely on external sources of heat to maintain their internal temperature. Another limiting factor could be their specialized diet requirements, as they primarily feed on insects and need a varied diet to stay healthy. Environmental factors such as habitat destruction and climate change can also be limiting factors for chameleons.

A commonplace idea before Virchow was the theory of spontaneous generation, which proposed that living organisms could arise from non-living matter under certain conditions. This idea was widely accepted until the mid-19th century when Virchow's principle of biogenesis, which stated that living cells only come from pre-existing living cells, gained prominence.

Molds are a type of fungi that are shapeless and fuzzy. They typically grow in moist environments and have a fuzzy appearance due to their mycelium, which is the thread-like structures that make up the body of the mold.

Limiting factors are environmental conditions that restrict the growth or distribution of a population. Temperature can impact biological processes, sunlight is crucial for photosynthesis in plants, and water availability is essential for hydration and nutrient transport in organisms. These factors can influence the ability of organisms to survive and thrive in a specific habitat.

A non-native plant in an ecosystem can outcompete native plant species for resources like sunlight, water, and nutrients, leading to a decrease in biodiversity. This can disrupt the balance of the ecosystem and impact wildlife that rely on native plants for food and shelter. Additionally, non-native plants may not have natural predators in the new environment, allowing them to spread rapidly and become invasive.

The prefix for ecosystem is "eco-".
