How changes in energy availability affect organisms
Changes in free energy availability can result in disruptions to an ecosystem. Change in the producer level can affect the number and size of other trophic levels. Change in energy resources levels such as sunlight can affect the number and size of the trophic levels.

What are 4 factors that affect energy availability
Physical factors, cost of exploitation and production, technology and political factors.
What are the factors which affect the availability of organisms
Some of the abiotic, or nonliving, factors that affect organisms' ability to survive include temperature, light availability, soil type, water, salinity levels, pH levels, nutrient levels, topographical features and altitude.
What are three 3 factors which affect our energy requirements
ESTIMATING ENERGY REQUIREMENTSResting Energy Expenditure. Unless levels of physical activity are very high, resting energy expenditure (REE) is the largest component of total energy expenditure.Physical Activity.Metabolic Response to Food.Age.Sex.Growth.Body Size.Climate.
What are the 3 factors of energy
TEE includes three core components: resting metabolic rate, or resting energy expenditure (REE); the thermic effect of food (TEF), also referred to as diet-induced thermogenesis (DIT); and physical activity.
What are the two factors that affect living organisms
Environmental Factors Affecting Living OrganismsAbiotic factors: non-living factors e.g. aspect: north-facing slopes are cooler and darker than south facing slopes in Northern hemisphere.Biotic factors: living factors, e.g. food availability: more food will enable more organisms to live.
What are the factors affecting capacity
A number of factors can affect capacity—number of workers, ability of workers, number of machines, waste, scrap, defects, errors, productivity, suppliers, government regulations, and preventive maintenance.
What are the factors affecting energy
There is a range of factors that affect the availability of energy, including physical factors, cost of exploitation and production, technology and political factors.
What are two other factors that affect a person’s energy requirement
Gender, age and body weight are the main determinants of total energy expenditure. Thus, energy requirements are presented separately for each gender and various age groups, and are expressed both as energy units per day and energy per kilogram of body weight.
What are the two factors of energy
Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed.
What two factors determine energy
Kinetic energy is determined by the following two factors:Mass of the body, m.Velocity of the body, v.
What are the 2 main factors that affect ecosystems
Ecosystems are influenced by both biotic and abiotic factors. Biotic factors include animals, plants, fungi, bacteria, and protists. Some examples of abiotic factors are water, soil, air, sunlight, temperature, and minerals.
What are the 2 important things in biological factor
Biological factors include genetic influences, brain chemistry, hormone levels, nutrition, and gender. Here is a closer look at nutrition and gender and how they affect development.
What are two factors that affect carrying capacity
Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few key factors: food availability, water, and space.
What are 3 factors that affect carrying capacity
Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates.
What are two factors that affect energy requirements
ESTIMATING ENERGY REQUIREMENTSResting Energy Expenditure. Unless levels of physical activity are very high, resting energy expenditure (REE) is the largest component of total energy expenditure.Physical Activity.Metabolic Response to Food.Age.Sex.Growth.Body Size.Climate.
What factors affect energy balance
Physical activity amounts to about 20 to 30 percent of the body's total energy output. Energy expended during physical activity varies with the level and duration of the activity. It is also affected by the age, gender, height, and weight of the individual performing the activity.
What are the 2 factors that affect kinetic energy
Explain that there are two factors that affect how much kinetic energy a moving object will have: mass and speed. Have students complete this demonstration to learn how mass influences an object's kinetic energy.
What are the two 2 major forms of energy describe each
After hundreds of years of observation and experimentation, science has classified energy into two main forms: kinetic energy and potential energy. In addition, potential energy takes several forms of its own. Kinetic energy is defined as the energy of a moving object.
What are the two 2 factors that affect energy balance
As mentioned above, when there is more energy going in than going out, you are in a state of positive energy balance. Being in a state of positive energy balance can be affected by both having too high of an intake or too low of an output, or a combination of both.
What are the 2 main types of energy
Many forms of energy exist, but they all fall into two categories:Potential energy.Kinetic energy.
What are the factors that affect ecosystem stability
They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.
What are 2 factors that causes environmental conflicts
The most common environmental elements around which conflicts can erupt are water flow, diversion, salinization, floods and pollution. 2. Indirect international or indirect intranational conflict are commonly caused by resource depletion issues – deforestation, soil erosion, desertification, flooding and pollution.
What are 2 human factors
Introduction to human factorsThe job: including areas such as the nature of the task, workload, the working environment, the design of displays and controls, and the role of procedures.The individual: including his/her competence, skills, personality, attitude, and risk perception.
What are two 2 biological factors that affect growth and development
Biological factors include genetic influences, brain chemistry, hormone levels, nutrition, and gender. Here is a closer look at nutrition and gender and how they affect development.
