Human exploitation of fragile ecosystems can lead to the droughts and arid conditions characteristic of desertification. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing.
The possible genotypes for the plant are Rr Rr rr rr. So there is a 0% chance
The average daily dietary fiber recommendations are 38 grams and 25 grams for male and females respectively. Dietary fiber is the indigestible portion of food that is usually derived from plants. It includes soluble fibers found in peas, beans, apples among others and the insoluble fiber, which promotes the movement of material through the digestive system and increases the bulk of the stool.
Photorespiration limits casualty products of light reactions
that build up in the absence of the Calvin cycle. In many plants,
photorespiration is a problem because on a hot, dry day it can drain as much as
50% of the carbon fixed by the Calvin cycle. The closing of stomata reduces access to CO2
and causes O2 to build up. These conditions favor a seemingly not useful process
called photorespiration. In most plants
(C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon
compound. In photorespiration, rubisco
adds O2 instead of CO2 in the Calvin cycle. Photorespiration eats up O2 and
organic fuel and releases CO2 without producing ATP or sugar. Photorespiration
can evolve relic because rubisco first evolved at a time when the atmosphere
had far less O2 and more CO2.
Answer:
The correct option is <em>A. decline, overshoot</em>
Explanation:
Carrying capacity can be described as the maximum number of a particular population size that an ecosystem can hold. The resources such as food, water, space etc are enough for a specific number of species. Sometimes, when a population diebacks, there are more number of resources present than the consumers, so the consumers start to reproduce and expand. The population of these organisms then might overshoot the carrying capacity.
