why cant food chain be indefinitely long
Answer:
Because:
Explanation:
Some energy is lost gradually in several ways at each trophic level:
Energy is lost through respiration, generating heat at each trophic level.
Energy is lost through waste (waste through excretion, feces, leftovers, etc. or energy lost through shedding of leaves in plants, shedding, molting of animals, ..) at each trophic level.
The higher the food chain (or trophic level), the less energy accumulates and to a certain extent there is no longer enough to maintain a link (of a trophic level). When a link (actually a species or group of card fish of a species) has too few individuals (smaller than the minimum size of the population) will not exist.
Which results from an increase in the greenhouse effect?
Increases in the different greenhouse gases have other effects apart from global warming including ocean acidification, smog pollution, ozone depletion as well as changes to plant growth and nutrition levels.

An event occurred that affected the population And when the scientist return the amount of genetic variation had
decreased significantly which of the following is most likely the event that occurred to change the population
In genetic variation, A population of wolves was introduced into Yellowstone National Park is most likely to happen.
What do you mean by genetic variations?The presence of distinct gene sequence variations among distinct species organisms is known as genetic variation. It empowers regular choice, one of the essential powers driving the advancement of life.
The change in a population's genetic makeup is known as genetic variation. All of a gene's variants, or alleles, are passed down from parents to offspring, giving them their unique characteristics.
Hereditary variety assumes a worthwhile part in the populace since it leans toward certain people to adjust to the climate. Change, quality stream, sexual generation, irregular mating between organic entities, arbitrary preparation.

Why are forests important for helping to control the rate of climate change?
Answer: Forests are a stabilizing force for the climate. They regulate ecosystems, protect biodiversity, play an integral part in the carbon cycle, support livelihoods, and supply goods and services that can drive sustainable growth.
Explanation:
The forest helps to maintain ecological balance, carbon cycle and rainfall.
How forest maintains ecological balance?"Ecological balance is a state of dynamic equilibrium within a community of organisms in which genetic, species and ecosystem diversity remain relatively stable, subject to gradual changes through natural succession."The forest prevent soil erosion and maintain soil fertility. It establish oxygen and carbon balance in nature.It absorbs harmful gases like carbon from environment. What is carbon cycle?"The carbon cycle is biogeochemical cycle by which carbon is exchanged among the biosphere, hydrosphere and atmosphere of the earth."Forests takes up carbon from atmosphere and gives out oxygen.Forest helps in decay, disturbance and renewal of carbon.Hence, the forest regulate rainfall, ecological balance and carbon cycle.

Which choice refers to a single population?
The diagram illustrates plants and two different zones of a deep lake.
In the upper part of the photic zone, organisms carry out both photosynthesis and cellular
respiration. Deep in the aphotic zone, only cellular respiration occurs.
Which statement is the most likely reason photosynthesis does not occur in the deepest
aphotic zone?
A)Sunlight for photosynthesis does not reach the deepest aphotic zone.
B) Water pressure limits the survival of animals in the deepest aphotic zone.
C) Not enough soil is present to support plant growth in the deepest aphotic zone.
D) Not as much dissolved oxygen from the surface reaches the deepest aphotic zone.
Answer:
A
Explanation:
B, C, and D all don't make sense, B doesn't talk about photosynthesis at all, same for C and D.
For photosynthesis to occur sunlight is of utmost importance. Therefore, option (A) is the reason why photosynthesis does not occurs in aphotic zone .
What do you understand by aphotic zone ?
The vast majority of the ocean's water may be found in the zone that is the deepest and darkest, known as the aphotic zone. This zone is directly below the photic zone and is characterized by its absence of light.
In the aphotic zone, there is not a single viable plant to be found. In the aphotic zone, there is no exposure to sunlight. Because they need light to create their food from carbon dioxide and water, plants are unable to live in an environment that is devoid of light (the aphotic zone).
The aphotic layer encompasses around 90 percent of the ocean.
Therefore, option (A) that is sunlight for photosynthesis does not reach the deepest aphotic zone is correct.

How does the chain of amino acids determine the shape of a protein?
Answer:
ok mark me brainliest also have a good day
Explanation:
A protein's shape is determined by the sequence of amino acids that make up the protein. The order of the amino acids, or the primary structure, determines the folding of the amino acid chains or tertiary structure. The interactions between the side chains and the amino acids determine the folds of the protein. and The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain, which ultimately determines the protein's unique three-dimensional shape. ... The final shape adopted by a newly synthesized protein is typically the most energetically favorable one.
Need help why are producers different from consumer and why are consumers diffrent from producers 5 paragraph summary
Answer: The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both. Organisms that eat only producers (i.e., plants) are called herbivores. Animals that eat only consumers (i.e., meat) are called carnivores.
Producers are organisms that can make its own food while Consumers are organisms that obtain energy by feeding on other organisms. Producers are commonly called autotrophs. In the food chain, heterotrophs are primary, secondary and tertiary consumers. An Example of Producers are green plants. An Example of consumers are animals.
In response to shortened day length and cool temperatures in the fall, many trees begin a period of senescence when the breakdown of chlorophyll exceeds chlorophyll production. The leaves of these trees appear to change to yellow and orange. Using your knowledge of photosynthetic pigments, explain the source of these yellow-orange hues.
Answer:
In response to shortened day length and cool temperatures, many trees begin a period of senescence where the breakdown of chlorophyll exceeds chlorophyll production. The leaves of these trees appear to change to yellow and in orange.
Xanthophylls and carotenoids are the pigments that result in the yellow-orange colour of leaves mostly occuring in the senescent leaves.
What is meant by senescence?
It is the process by which leaves get deteriorated with age and the power of division and growth is lost. It occurs throughout the lifespan including embryogenesis. It plays an important role during development as well as wound healing.
Cold temperature can decrease the plant's enzymatic activity and disrupts the plant's nutrient intake this results in a decrease in the growth of the plant and causes senescence.
Events that occur during senescence in plants include:
Disintegration of chloroplastsbreakdown of leaf proteinsloss of chlorophyllCessation of photosynthesisLeaf senescence is primarily associated with aging. It can also be induced by environmental inputs including biotic and abiotic stresses.
During senescence, cessation of cell division and permanent withdrawal from the cell cycle occurs and the leaves fall after they change colour to yellow and orange because of pigments xanthophyll and carotenoids.
