Carrying capacity

Overall, these properties allow it to: provide habitats for animals; transport substances around organisms; regulate and participate in cell reactions and help animals maintain a constant blood temperature. Water’s small size is important for plants as it is able to diffuse by osmosis into plant cells which creates turgor as the vacuole swells pressing against the cell wall. This pressure helps plants stand up straight and not wilt causing death As water is lost by transpiration from the…

The term Thermochemistry refers to when heat is evolved or absorbed during a chemical reaction. When calculating the amount of energy, the number will always be expressed as a positive number. A negative sign will indicate whether the energy is evolved or absorbed. If the sign is negative, then the energy is evolved and if the sign is positive, then the energy is absorbed. The amount of heat that is released or absorbed will also be in units of Joules or Kilojoules per mol. There are two other…

Evaporation: The rate of heat transfer in the evaporator is calculated using equations 10 and 11 Q_in=(εC)_evap (T_(in,evap)-T_evap ) (10) Where ε is the effectiveness of the evaporator, C is the capacitance rate for the air or chilled water passing through the evaporator. Tevap is the temperature of refrigerant in evaporator and Tin, evap is the temperature of the air or chilled water at the inlet of the evaporator. Equation 11 express Qin in terms of enthalpy. Q_in=m ̇_ref (h_4-h_1)…

consequence of a decrease in the specific heat capacity of the solution compared to pure water. The specific heat capacity drops because the specific heat is lower for salt. Hence, when water is mixed with salt the specific heat value drops. In other words, it takes less energy to raise the temperature of the salt water by 1K than pure water. This means that the salt water heats up faster and eventually gets to its boiling point first. The heat capacity of NaCl has been found to be higher than…

Abstract: The purpose of this lab was to show the different absorption and emission rates of three different substances. Radiation laws, albedo, and specific heat are all reasons why this is achievable. An agreed upon hypothesis is that the sand will absorb the most heat due to the number of molecules, the moss will absorb the second most because it doesn't have as many molecules as sand, but it has more than water, which isn’t as complex. To complete this experiment, you need three beakers of…

Pectin yield was determined as weight of dry pectin against the weight of initial residues multiplied by 100%. Y=100(P/Bi) Where Y is the extracted pectin yield (%), P is the amount of extracted pectin in grams and Bi is the initial amount of sweet potato residues used to extract pectin. Equivalent weight and Degree of methoxylation The equivalent weight was determined according to the method by Barretina et al., (Barretina et al. 2012). 0.25g pectin was wetted with 5ml ethanol and topped…

INTRODUCTION According to Miller and Spoolman (2010), carrying capacity is defined as “the maximum population of a given species that a particular habitat can sustain indefinitely” (Miller & Spoolman, 2010). Figure 5-8 p. 86 (Miller and Spoolman, 2010) As seen in the carrying capacity graph above, “no population can continue to grow indefinitely because of limitations on resources and because of competition among species for those resources” (Miller and Spoolman, 2010). As the population…

higher capacity of a whale. The whale is the predator to the seal, which is the prey. However, if the death rate of whales increases then, the population of seals will increase also. Only, the seal population will increase because with the decrease of whales the seals have a higher chance of living, especially with the fact that seals birthrate is higher than whales. Furthermore, the carrying capacity of seals are increased, the same will be for whales. The effect of the carrying capacity in…

population will begin to level off until they hit its carrying capacity point. 3. IDENTIFY TWO examples of density independent factors. DESCRIBE how density independent factors affect the size of a population. ANSWER: Independent factors could potentially be a fire or a flood. Density independent factors…

to sustainable tourism, which actively seeks to draw links between the local and the global, measurements of carrying capacity concentrate on local factors when evaluating the limits to tourism development or tourism usage of a resource, whether this is a destination, attraction, or any other spatially defined unit of the tourism industry. There is not one simple measure of carrying capacity that can be evenly and equally applied to all destinations and attractions because they are not…
