Ecology and Bionomics

An ecological succession is the process by which an ecosystem changes in structure and composition over time. It typically involves a gradual transition from one type of community to another, driven by factors such as species interactions, environmental conditions, and disturbances. This can lead to the replacement of one species by another as the ecosystem progresses through different stages.

If balance in nature is destroyed, it can lead to disruptions in ecosystems, loss of biodiversity, and negative impacts on human health and well-being. This could result in species extinction, altered weather patterns, and imbalances in food chains, ultimately affecting the overall stability and sustainability of the environment.

Some ecological backlashes we're experiencing right now include habitat loss, species extinction, climate change resulting in extreme weather events, and plastic pollution in oceans and waterways. These backlashes are the results of human activities such as deforestation, overfishing, burning of fossil fuels, and inappropriate waste disposal.

Ecology is the study of the interactions between organisms and their environment, including other organisms, climate, and physical resources. It explores how different organisms influence each other and their surroundings in ecosystems.

Merit: Green Revolution led to increased food production, reduced hunger and malnutrition, and supported economic growth in many developing countries.

Demerits: It has been criticized for its heavy reliance on chemical fertilizers and pesticides, leading to environmental degradation, soil health issues, and loss of biodiversity. Additionally, it widened the gap between wealthy and poor farmers, increasing income inequality.

Archebacteria obtain their energy through various metabolic pathways such as chemosynthesis, where they harness chemical energy from inorganic compounds like sulfur or iron. They can also utilize sunlight through a process called phototrophy to produce energy. Additionally, some archebacteria can derive energy from organic molecules through fermentation or respiration.

The badlands ecosystem is characterized by arid conditions, eroded landscapes with steep slopes and sedimentary rock formations. Vegetation is sparse, consisting of drought-resistant plants like grasses, shrubs, and cacti. Wildlife in the badlands includes species adapted to the harsh environment, such as bighorn sheep, pronghorn, coyotes, and various reptiles and birds.

The amount of salt extracted from the sea water is insufficient to have any significant environmental impact, and present rates of extraction are nowhere near high enough to cause one.

Ocean salinity is the result of cyclical process that began when the first drop of water became part of planet Earth. The extraction of salt from the sea, just adds another step to this cycle.

The oceans naturally vary in salinity from about 3.1 - 3.8 %, due to river inflows, localized precipitation rates, ocean currents, up-wellings, and other causes. These natural variations are much larger than present rates of extraction can possibly cause, even in areas close to extraction operations.

Sink ecology refers to an ecological concept where a habitat has low resources or unfavorable conditions for a particular species or population, leading to decreased survival and reproduction rates. Sink habitats can attract individuals because they are similar to source habitats, but they ultimately result in reduced fitness and may not contribute to long-term population growth or persistence.

Yes, response to stimuli is a characteristic of living things. This ability allows organisms to react to changes in their environment, enabling them to survive and thrive.

Ecology can drive evolution by selecting for traits that are beneficial for survival in a particular environment. Environmental factors such as competition for resources, predation, and habitat availability can influence which traits are favored and passed on to future generations. Over time, this can lead to the adaptation of populations to their specific ecological niches.

When a cell is not in use, there can still be a small amount of current flowing through it due to internal factors like self-discharge or leakage currents. This internal current can lead to a drop in the cell's electromotive force (EMF) over time, even when the cell is not actively powering a device.

Ecology is the study of how living things interact with their environments. It is important to know how living things will change in response to human intervention, whether species will thrive or go extinct.

Approximately 70% of the biomass produced by plants in oceans is accounted for by phytoplankton. Phytoplankton are tiny, photosynthetic organisms that form the base of the marine food chain and play a crucial role in marine ecosystems.

A natural spring would be one, an artesian basin another, and underground streams (such as found in cave systems) another again. Possibly a water well would be the commonest example. The above only consider land based systems.

Leopards play a crucial role in regulating prey populations in savannas by controlling herbivore numbers. They help maintain a balance within the ecosystem by preying on a variety of species. Harpy eagles act as top predators in the rainforest, controlling populations of smaller animals within the food chain. They play a vital role in maintaining the health and balance of the rainforest ecosystem.

It is difficult to provide an exact number as it varies depending on individual habits and needs. However, on average, most people may use 1-3 spray cans per day for various purposes such as personal care products, cleaning, or household maintenance.

1. Preserve biodiversity by studying interactions between organisms and their environment.
2. Improve understanding of ecosystems, leading to better conservation and management strategies.
3. Inform environmental policy and decision-making by providing important data on ecosystems.
4. Help address environmental challenges such as climate change and habitat destruction.
5. Enhance public awareness and appreciation of the natural world, fostering a sense of responsibility towards the environment.

The trophic level most affected by environmental toxins such as DDT is usually the top predators, such as apex predators or carnivorous animals. This is because toxins bioaccumulate as they move up the food chain, reaching higher concentrations in organisms at higher trophic levels.

These plants produce biochemicals that can actually influence the growth of other plants. So, when these plants want space they can influence other plants not to grow near that space, to grow smaller so they can not compete for that space or even in some rare cases have the plant put all it's resources into either reproductive structures or growth so it can not be successful in one or the other.

Oysters and Oyster Borers have a predator-prey relationship. Oyster Borers are a type of marine snail that feeds on oysters by boring into their shells, weakening and eventually killing the oysters. This relationship can have negative impacts on oyster populations and can disrupt marine ecosystems.

Ecologists study a variety of interactions between organisms and their physical environment within a certain area, such as nutrient cycling, energy flow, competition for resources, predator-prey relationships, and the influence of abiotic factors like temperature, rainfall, and soil composition on the distribution and abundance of species. These interactions are essential for understanding ecosystem dynamics and how species coexist in a given habitat.

A period of time where organisms survive unfavorable conditions is called dormancy. During dormancy, organisms enter a state of reduced activity and metabolic rate to conserve energy and resources until conditions improve. This adaptation helps organisms to survive harsh environments or seasonal changes.

Factors such as availability of resources, competition, predation, disease, environmental changes, and genetic diversity can impact whether a population thrives or declines. Populations that have access to abundant resources, low competition, and effective defense against predators and diseases are more likely to thrive, while populations facing scarcity, high competition, or environmental stress are more likely to decline. Additionally, genetic diversity within a population can influence its ability to adapt to changing conditions.

A nonnative species can disrupt the balance of an ecosystem by outcompeting native species for resources, preying on native species, introducing diseases, or altering the physical habitat. This can lead to declines in native species populations, changes in species interactions, and overall ecosystem instability.
