It is believed that mitochondria and chloroplasts are known to be energy converting organelles. Some components of the cells carry the ability to work as small machines and are responsible for withdrawing energy from the chemical bonds found in the ultimate source of nourishment in all living cells called glucose.
The mode of particle transport which needs the input of energy from the cell is called active transport. Active transport, in cell biology, refers to the movement of the molecules through the membrane against the concentration gradient, which means from an area of lower concentration to an area with higher concentration.
Further Explanation:
The energy converting organelles of the eukaryotes is developed from the prokaryotes which were engulfed by the primitive eukaryotic cells. This evolved a symbiotic relationship between them. This explained the reason behind mitochondria and chloroplasts having their own DNA or deoxyribonucleic acid which encodes for certain proteins.
Energy processing in plants is fundamentally similar to that of animals and most fungi. The ultimate objective is to split down the glucose into smaller molecules and absorb the ATP or adenosine triphosphate molecules. Mitochondria are known to be the powerhouse of the cell as they are the sites for aerobic respiration.
Chloroplasts, on the other hand, stores the chlorophyll in tiny bags called thylakoids. In this process, the plants use light energy in order to produce ATP and NADPH which are known to be energy-carrying molecules and then produce glucose by using this energy.
Active transport is of two kinds,
Primary active transport utilizes adenosine triphosphate while secondary one uses an electrochemical gradient. A typical example of active transport is the uptake of glucose in the intestines in human physiology.
The movement of the ions and other molecules through the membrane of the cell without any requirement of the energy input refers to passive transport. This process does not require any input of the cellular energy as it is driven by the ability of the system to develop in entropy. There are four types of such transport, namely, filtration, osmosis, facilitated diffusion and simple diffusion.

The Jurassic period had angiosperms, while the Cretaceous did not.
b.
Pangaea split during the Jurassic period.
c.
There were dinosaurs in the Jurassic period, which went extinct in the Cretaceous period.
d.
Conifers and ferns were present in the Jurassic period, but not in the Cretaceous period.
The Cretaceous period differs from the Jurassic period in that there were dinosaurs in the Jurassic period that became extinct in the Cretaceous period, as the dinosaurs that were available in the Jurassic period are in Option C.
They were significant as they were the dominant land animals during the Mesozoic Era and evolved into a wide variety of forms, from the large, long-necked sauropods to the small, agile raptors, and they gave insights into the evolution of life on Earth. Dinosaurs help scientists understand the patterns and processes of evolution, including how animals adapt to changing environments and showed the link with birds.
Hence, the Cretaceous period differs from the Jurassic period in that there were dinosaurs in the Jurassic period that became extinct in the Cretaceous period, as the dinosaurs that were available in the Jurassic period are in Option C.

b. autotrophs are simpler organisms than heterotrophs
c. heterotrophs only generate a small fraction of their energy from photosynthesis.
d. all of the above
Answer: Option A
Explanation:
Only autotrophs have the ability to convert solar energy into chemical energy by the process known as photosynthesis. The autotrophs can trap all the radiant energy and only 10% of total energy that autotrophs have is transferred to another tropic level.
The energy from the producers are transferred to the herbivores and 10% of the total energy the herbivores have is transferred to another levels.
So, the energy flow takes place through the autotrophs because only they have the ability to perform photosynthesis.
