Answer

. Plants breathe through pores PRESENT on their leaf SURFACE called stomata. Oxygen in the air GETS dissolved in water EXISTING in plant tissues. This dissolved oxygen is utilised for respiration. Also plants get their oxygen from the process of photosynthesis, as oxygen is BYPRODUCT of this process.

Answer:

In physics, a force is any interaction that, when unopposed, will CHANGE the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be DESCRIBED intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity.

Explanation:

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a GENERATOR to create electricity. The steam is then cooled, CONDENSED back into WATER and returned to the boiler to start the process over.

Answer:

Despite expanding human populations in metropolitan areas world-wide, habitat relationships of lizards have seldom been examined along urban gradients. We tested three hypotheses addressing lizard species distributions, site occupation, and assemblage organization along the urban gradient in Tucson, Arizona, USA. One hundred twenty-nine random sampling plots were distributed from undisturbed-natural land beyond the boundary of DEVELOPMENT to highly developed land within the city. We recorded lizard species abundances and 19 VARIABLES describing habitat physiognomy, floristics, and spatial relationships of native remnant and developed land parcels in each plot. We ordinated lizard species and habitat data in a canonical correspondence analysis, and tested significance of relationships in a Monte CARLO randomization TEST. We then tested effects of individual habitat features on site occupation by lizards using a presence–absence transformation of lizard abundance data and multiple logistic regression. Both species distributions and site occupation were influenced by factors describing habitat physiognomy, floristics, and landscape spatial relationships. Finally, we examined TOTAL abundance, number of species, and evenness across five categories describing increasing residential density. All three measures of assemblage organization peaked at low–moderate levels of development, and declined markedly as residential density increased beyond moderate levels. Distinct attributes of urban development influence lizard species distributions, site occupation, and assemblage organization. Attention to these attributes will allow land developers to mitigate the effects of future urban development on lizard populations.

ANSWER:

CARBON moves from living THINGS to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process CALLED respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.

Photosynthesis, DECOMPOSITION, Respiration and Combustion.

During photosynthesis, plants use carbon dioxide and produce oxygen. During metabolism oxygen is used and carbon dioxide is a product.

Explanation:

A simple machine is a mechanical device that CHANGES the direction or magnitude of a force. In general, they can be defined as the SIMPLEST MECHANISMS that USE mechanical advantage (also called leverage) to multiply force.

Answer:

A switch is a SIMPLE device that either breaks the circuit or COMPLETES it. When switch is in 'OFF' POSITION, then the circuit is OPEN i.e. no current flows through the circuit and when switch is in 'ON' position, then the circuit is COMPLETE i.e. current flows through the circuit.

Explanation:

Biomagnification Definition

“Biomagnification or biological magnification is the process of accumulation of certain chemicals in living organisms to a concentration higher than that occurring in the inorganic, non-living environment.”

What is Biomagnification?

Biomagnification can be defined as the rise or increase in the contaminated substances caused by the intoxicating environment. The contaminants might be heavy metals such as mercury, arsenic, and pesticides such as polychlorinated biphenyls and DDT.

These substances are taken up by the organisms through the food they consume. When the organisms in the higher food chain feed on the organisms in the lower food chain containing these toxins, these toxins get accumulated in the higher organisms.

Lets us have a look at the causes and consequences of biomagnification.

Causes of Biomagnification

Following are the major causes of biomagnification:

Agriculture

The agricultural pesticides, INSECTICIDES, fertilizers and fungicides are very toxic and are released into the soil, rivers, lakes, and seas. These substances contain small amounts of heavy metals such as mercury, arsenic, COPPER, lead and cadmium. These cause health issues in aquatic organisms and humans.

Organic Contaminants

Manures and biosolids are processed industrially and contain contaminants like pharmaceuticals and personal care products. These substances have an adverse impact on the health of humans, animals, and wildlife.

Industrial Activities

The INDUSTRIES and factories release toxic substances that are released into the soil, lakes, oceans, and rivers. The gaseous emissions pollute the environment which enters into the food chain leading to biomagnification.

Mining Activities in the Ocean

Mining activities are carried out in the deep sea to extract metal like zinc, aluminium, cobalt, silver and gold. The mining process generates a large amount of selenium and sulphide, which deposits in water and destroys the oceans and coastal regions.

The level of toxicity is increased. These toxic substances are absorbed by the aquatic organisms higher in the food chain.

Effects of Biomagnification

Following are the effects of biomagnification on living organisms and the environment:

Impact on Human Health

Biomagnification makes humans more prone to cancer, kidney problems, liver failure, birth defects, respiratory disorders, and heart diseases.

Effects on Reproduction and Development of Marine Creatures

The toxic chemicals accumulate in the important organs of aquatic organisms that affect their reproduction and development processes.

For eg., the shells of the eggs of the sea-birds are very thin that might get crushed by the birds themselves during incubation. The toxic chemicals, mercury and selenium destroy the reproductive organs of aquatic creatures.

Destruction of Coral Reefs

Cyanide that is USED in leaching gold and fishing is the main cause of the destruction of coral reefs. Coral reefs are the dwelling and feeding grounds for many sea creatures. Their destruction affects the lives of many aquatic animals.

Disruption of Food Chain

The chemicals and toxins which are released into the water bodies disrupt the food chain. The small organisms absorb the toxins which are eaten up by larger animals. These toxins, thus, get accumulated in the higher level of organisms.

Answer:

d - decomposers

Explanation:

producers take carbon from ENVIRONMENT so as consumers though they take from producers

scavengers take dead things as FOOD (almost a CONSUMER) so CANT be one of the who will release carbon from dead things into the environment

decomposers decay almost EVERYTHING of dead things and release or give back carbon them to the environment

hence, decomposers is the answer.

Explanation:

Answer:

Oil spills in the ocean and SEAS are a very big threat to marine life as oils destroys the insulating ability of fur-bearing mammals, such as sea OTTERS, and the water repellency of a bird's feathers, thus EXPOSING these creatures to the harsh elements. Without the ability to repel water and INSULATE from the cold water, birds and mammals will die from HYPOTHERMIA.
