The most appropriate answer is D !
in respiration oxygen and glucose( food substance) combines to form energy and CO2 !
Abiotic variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight. The boundaries of an individual abiotic factor can be just as unclear as the boundaries of an ecosystem.These are often referred to as abiotic factors. Abiotic factors are non-living elements found within an ecosystem. There are six abiotic factors that affect plant growth: air, water, space, temperature, light and soil (nutrients).The two most important abiotic factors affecting plant primary productivity in an ecosystem are temperature and moisture.
LEARNING OBJECTIVE[ edit ]
Identify the abiotic factors that affect plant growth
KEY POINTS[ edit ]
Primary production, on which almost all of life on earth is dependent, occurs through either photosynthesis or chemosynthesis.
Annual biomass production, used to estimate net primary productivity by plants in an area, is directly influenced by an environment's abiotic factors, which include temperature and moisture.
Warm and wet climates have the greatest amount of plant biomass because they offer conditions in which photosynthesis, plant growth, and the resulting net primary productivity are highest.
TERMS[ edit ]
biomass
the total mass of all living things within a specific area, habitat, etc.
eco-region
a region, smaller than an ecozone, that contains a distinct biodiversity of flora and fauna
chemosynthesis
the production of carbohydrates and other compounds using the oxidation of chemical nutrients as a source of energy rather than sunlight; it is limited to certain bacteria and fungi
Answer:
Comparative genomics of the three groups
Explanation:
The comparative genomics of the three groups was used to determine their evolutionary distinctiveness. Comparative genomics is a powerful tool used to study evolutionary changes among organisms, it helps to identify gene similarities and differences among organisms.
Bacteria and archaea (formerly called archaebacteria) were considered much more closely related, but DNA sequence analysis showed numerous differences between the two groups, and further proved that archaea was closely related to eukarya than bacteria.
However, in 1970, Dr. Carl Woese and other scientists in a bid to determine the distinction between the three groups made use of the nucletide sequence of the ribosomal RNA as an evolutionary time clock.
It is widely known that the rRNA sequences; is present in all organisms, functions differently in various organisms, is involved in protein synthesis, can be align between two organisms and can change gradually over a long period, hence this made it a good tool to determine evolutionary distinctiveness.

Answer:
Logistic growth
Explanation:
Logistic growth is a type of population growth whereby the rate at which the population of living organisms grow or increase in size quite rapidly.
During logistic growth, the population of organisms are studied or tracked for a period of time after which the growth rate declines due to a decrease in the availability of resources , hence the environment cannot aid in the growth of these organisms.
