Is photosynthesis the ONLY driver for cycling matter and energy in ecosystems? yes or no
Do not play on my question please.
The
store(s) more carbon than the atmosphere.
O rock
trees
oceans
Osoil
Answer:
Oceans
The oceans are a massive carbon sink, and part of the positive reinforcement of the greenhouse gas cycle is that, as the oceans become warmer, then tend to release more carbon dioxide dissolved in the water which in turn drives temperatures warmer.
Explain how the formation of a submergent coastline differs from the formation of an emergent
coastline.
Answer:
One occurs when sea level rises whereas the other happens when the sea level drops.
Explanation:
The main difference between Submergent coastlines and emergent coastlines because Submergent coastlines formed when sea level rises or in other words, the land sinks down. Examples of submergent coastlines are estuaries, barrier bars, and barrier island systems while on the other hand, emergent coastlines occurs when sea level drops or the land rises. Hudson Bay and Eastern Coastal Plains are the examples of emergent coastlines.

What would happen if there were no greenhouse gases to trap heat?
Answer:
The Earth would be covered in ice and be about -18°C in temperature.
Explanation:
Greenhouse gases in the air, mainly carbon dioxide, methane and water vapour, trap radiation from the Sun and work as a thermal blanket around the planet. Without the Greenhouse effect, the Earth would be ice-cold.

Explanation:
The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops
Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.

What is boiling factor ?
The boiling factor of a liquid varies in keeping with the carried out strain; the everyday boiling factor is the temperature at which the vapour strain is identical to the same old sea-degree atmospheric strain (760 mm [29.92 inches] of mercury). At sea degree, water boils at 100° C (212° F).
Thus it is well explained.

a. The improper or unsafe use of a drug
b. A drug that is inhaled as vapors
c. a drug that temporarily increases energy and alertness
d. drug withdrawal occurring in newborn infants
e. laboratory made drugs that closely resemble common illegal drugs in chemical structure and effect
f. a drug that slows the body and the brain
Answer:
a. Drug abuse
b. Inhalants
c. Stimulants
d. Neonatal abstinence syndrome
e. Club designer drugs
f. Depressants
Explanation:
Drug abuse can be defined as the excessive use of drugs that can be harmful to the individual or to others, which is associated with social, behavioral, physical and job-related problems. Inhalants drugs (e.g., glue, cocaine) are volatile drugs whose inhalation may induce psychoactive and/or mind-altering effects. Stimulant drugs (e.g., cocaine, amphetamines) are drugs that excite body functions by accelerating the activity of the central nervous system (CNS), while depressant drugs (e.g., alcohol) slow down the CNS. Neonatal abstinence syndrome occurs when a neonate withdraws from certain drugs (usually opioid drugs which interact with opioid receptors) to which he/she was exposed before birth. Finally, designer drugs (e.g., ecstasy, ketamine, LSD) are drugs synthesized in illegal labs which are commonly known as “club drugs” because they are often used and sold in nightclubs.

The principal reason we consider tunicates similar to the ancestor of all chordates is that Select one: a. tunicates have a lophophore-style mouth. b. tunicate adults are very similar to the ancestors of cephalochordates and vertebrates. c. tunicate larvae are primitive in all of their features. d. tunicate larvae possess the synapomorphies of adult chordates and thus reveal close evolutionary relationships with chordates. e. the body plan of adult tunicates parallels that of chordates.
Answer:
d. tunicate larvae possess the synapomorphies of adult chordates and thus reveal close evolutionary relationships with chordates.
Explanation:
In evolutionary biology, a synapomorphy is a shared, derived character/trait which is present in an ancestor and its descendants. Synapomorphies are useful markers to establish phylogenetic relationships between sets of taxa. Tunicates (subphylum Tunicata) are sessile marine invertebrates that are considered chordates (phylum Chordata) because the larval stage has characters/traits that are similar to other chordates. Larval tunicates have a nerve cord, a notochord, tail and gill slits (conserved in adults).

The graph below shows the population of mice living in a certain area over fifteen years Which numeral on the graph points to a time when the birth rate exceeded the death rate of the mice?
I
II
III
IV
Answer:
I
Explanation:
In section I, the graph has a positive slope.
Birth rate - death rate = positive, the birth rate is more than the death rate
Sections II and IV have a balanced population where the birth and death rate are the same
In section III the death rate exceeds the birth rate
The numeral I on the graph points to a time when the birth rate exceeded the death rate of the mice.
What is death rate?The mortality rate, also known as the death rate, is a measure of the number of deaths in a given population per unit of time, scaled to the population's size.
The birth rate is the number of people born in a population in a given period of time. The number of people born per year per 1000 in the population is referred to as the human birth rate.
In section I, the graph has a positive slope. Birth rate and death rate difference is positive here, it means the birth rate is more than the death rate.
Sections II and IV have a balanced population with the same birth and death rates. Section III has a higher death rate than a higher birth rate.
Thus, the answer is numeral I.
