Which process transfers energy from organisms at one stage in a food chain
to organisms at the next?
Tick the correct box.
reproduction
feeding
movement
photosynthesis
1 mark
Answer:
feeding
Explanation:
when an organism eats another, it gets energy from it. That energy is passed along the food chain
The process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.
What is the significance of the food chain and the energy transfer?The food chain in nature is made up of many trophic levels, where one trophic level animal preys on other animals or plants and obtains food from them, so when the animal is eaten by other animals, the energy content passes from one to another, and the energy content from plants continues to decrease to the topmost trophic levels.
Hence, the process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

Pioneer organisms modify the environment.Thus, the correct option for this question is D.
What is Ecological succession?Ecological succession may be defined as the gradual and continuous replacement of one community by another community over a long period of time.
Pioneer organisms are those organisms that arrive first in any ecosystem which is bare. The pioneer species are always found to be present in the bare area. The organisms that are the last organisms to appear known as climax organisms.
Pioneer organisms modify the environment in such a way that makes the bare atmosphere a little bit improved with respect to the need of other organisms.
Therefore, the correct option for this question is D.

The autonomic nervous system works without our control. Which of the following does
cardiac muscle fall under?
involuntary or
voluntary
Answer: Involuntary.
The Autonomic nervous system is a subdivision of the Peripheral nervous system and it is in charge of the involuntary processes in the body such as blood pressure, respiration and the heart rate. As such, its effectors are under involuntary control.
The Autonomic nervous system controls the smooth and cardiac muscles in the body as well as the glands. This is where it earns its other name, the Visceral nervous system.

19. Explain the following observation made by Gregory Mendel in his experiments, A cross between a
pure breed tall plant and a pure breed dwarf plant had all the first filial generation being tall.
Answer:
The correct answer is - can be explained by the law of dominance.
Explanation:
In this experiment of Gregory John Mendel where he made a cross between a purebred tall plant and a purebred dwarf plant and in the first generation all the offspring were tall.
It can be explained by that every offspring get one allele from both parents and in purebred both alleles are either dominant or recessive and both parent plant gives one allele which makes a heterozygous condition in which the dominant allele masks the recessive allele and offspring express phenotype of the dominant parent.

If the half-life of a radioactive atom is 3,500 years. How old is the substance if the parent-daughter ratio is 1:127?
Answer:
2.447 × 10⁴ years
Explanation:
Step 1: Given data
Half-life of the radioactive atom (t1/2): 3,500 yearsParent-daughter ratio ([A]/[A]₀): 1:127 (1/127)Step 2: Calculate the rate constant
Radioactive decay follows first-order kinetics. We can calculate the rate constant (k) using the following equation.
k = ln2 / (t1/2) = ln2 / 3,500 y = 1.980 × 10⁻⁴ y⁻¹
Step 3: Calculate the time elapsed (t)
For first-order kinetics, we will use the following expression.
ln ([A]/[A]₀) = -k × t
t = ln ([A]/[A]₀)/ (-k)
t = ln (1/127) / (1.980 × 10⁻⁴ y⁻¹) = 2.447 × 10⁴ y

The digestive system carries out chemical digestion while the excretory system does physical digestion.
Answer:
A. The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
Explanation:
got it right on edg quiz (see pic)
hope this helps :)
All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.
What is the digestive and excretory system?Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.
The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.
The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).
Therefore, the correct answer is a).
