Ecology and Bionomics

The concentration of DDT is lower in water than in organisms because of bioaccumulation. Organisms absorb DDT from water through their food or direct exposure, leading to higher concentrations in their bodies compared to the surrounding environment. As DDT moves up the food chain, its concentration increases at each trophic level, resulting in higher levels in organisms than in the water.

"Cellulosic" means that the material contains cellulose. Cellulose is found in wood, paper, grass and other plant matter. If it is used as a starting point for producing something, such as ethanol, that would make it a feedstock.

Whitehorse is located in the Boreal Cordillera ecozone. This ecozone is characterized by its mountainous terrain, boreal forests, and cold climate typical of northern Canada.

Overall, mushrooms are considered good for the environment. They play a crucial role in nutrient cycling and decomposition processes, breaking down organic matter and releasing nutrients back into the soil. Additionally, some species form mutually beneficial relationships with plants, enhancing their growth.

Environment is a natural location or area where humans live. It is therefore characterized as nature hence; humans has a natural relationship with the environment; in the sense of their habitation. Wheresoever there is life, there also is environment. As we have fishes environment which is the sea or water; likewise the human environment which is earth.

There is no life without environment, as it does not terminate at where man inhabit rather, spans to every space where there is existence. And humans, being the chiefest in creation; takes the domineering part of creation. Humans relationship with environment is that of existence otherwise; there is no space saved for his living. All other activities done by humans are as characterized by this relationship, e.g. planting, fishing, building to mention but few.

Green-lipped mussels have adapted by developing specialized shells that help them withstand wave action and protect them from predators. They also have a unique ability to filter feed, obtaining nutrients from the surrounding water. Additionally, they have a symbiotic relationship with certain types of algae that provide them with additional nutrients.

One example of a viral reproduction cycle that can cause rapid death is the lytic cycle. In this cycle, the virus enters a host cell, replicates quickly, and then bursts the cell open to release new virus particles. This rapid destruction of host cells can lead to severe damage to the host organism and potentially result in death.

Biotic factors of the Appalachian Mountains include plant and animal species such as black bears and hemlock trees. Abiotic factors include soil composition, temperature variations, and precipitation levels that influence the ecosystem's overall structure and function.

Beavers, elephants, termites, and prairie dogs are examples of animals that are considered ecosystem engineers. These animals significantly modify their environment through their activities, such as building dams, digging burrows, or creating nests, which can have a profound impact on the ecosystem around them.

Overfishing is an example of a human activity harming a renewable resource. It can lead to depletion of fish populations and disrupt the balance of marine ecosystems, making it harder for fish stocks to recover and reproduce.

Donor control in biology refers to the phenomenon where genetic material from one organism is used to control the expression of genes in another organism. This can happen, for example, in genetic engineering when genes from one organism are inserted into another to produce a desired trait.

The warmest aquatic ecosystem is typically found in coral reefs, where water temperatures can reach up to 86°F (30°C) or higher. This warm temperature is ideal for the growth of the coral reef organisms and supports a high level of biodiversity.

No, dragonflies are not an example of a heterotroph. They are actually carnivorous insects that feed on other small insects for their energy and nutrients. Heterotrophs are organisms that cannot produce their own food and rely on consuming other organisms for energy.

Glomeromycetes form arbuscular mycorrhizae, which are symbiotic associations with plant roots. They increase surface area for absorption of nutrients and water from the soil. The fungi obtain organic compounds from the plant cells. Absence of such endomycorrhizae reduces ability of plants to obtain nutrition. Many plants cannot survive in their absence.

Hiking from Gatlinburg to the peak of Mount LeConte is like traveling to Canada in terms of the significant change in elevation gain. Just as traveling to Canada would involve a distinct change in location and altitude, ascending from Gatlinburg to Mount LeConte involves a substantial elevation increase, providing a similar sense of accomplishment and change in scenery.

Many ecosystems rely on each other for balance and functioning. For example, forests and rivers are interdependent as forests help maintain water quality in rivers, while rivers provide water and nutrients essential for forest growth. Similarly, coral reefs and mangrove forests are interconnected, with mangroves providing protection for coral reefs against erosion and sedimentation.

The cell membrane separates the internal environment of the body from the external environment. It acts as a physical barrier that controls the passage of substances in and out of the cell, maintaining the cell's internal balance.

Decomposers break down dead organisms to produce nutrients like nitrogen, phosphorus, and potassium, which can enrich the soil. These nutrients help support plant growth and improve soil fertility.

No, archaebacteria do not have a membrane-bound nucleus. Instead, their genetic material is located in the nucleoid region of the cell, which is not enclosed by a membrane. This is a characteristic feature that distinguishes archaebacteria from eukaryotes.

Ecological balance is disturbed by man through activities such as deforestation, pollution, overfishing, and habitat destruction. These actions disrupt natural ecosystems and lead to loss of biodiversity, depletion of resources, and climate change. It is important for humans to adopt sustainable practices to restore and maintain ecological balance.

Ecology is essential on our planet as it maintains the balance of ecosystems, supports biodiversity, and provides resources such as clean air and water that are vital for life. Understanding and preserving ecology is crucial for the sustainability of our planet and the well-being of all living organisms.

People become vegetarians for various ecological reasons, such as reducing greenhouse gas emissions associated with meat production, minimizing water and land use for agriculture, and decreasing deforestation for livestock farming. Adopting a plant-based diet can help lower one's ecological footprint and support sustainable food systems.

Taking sample measures of species abundance allows for a more manageable and feasible way to gather data on a larger scale. It helps to provide a representative snapshot of the species present in an area, enabling researchers to identify patterns in species distribution and make inferences about the overall biodiversity and ecological dynamics of the ecosystem.

Field ecology is the study of organisms, the relationships between them, and the corresponding flows of energy and nutrients, in the environment in which they live. "Field" does not mean something like "meadow" in this case, but simply contrasts with "laboratory". So aquatic ecology in a river or lake might be described as field ecology. It includes techniques used for study eg. quadrates , sampling techniques etc.
