Match the wildlife management activities to their description controlling food supply
bezimeni [28]

Description of Wildlife Management Activities is given below.

Explanation:

Wildlife management is concerned with the preservation and improvement of habitats although rewilding is increasingly being used. Techniques can include reforestation, pest control, nitrification and denitrification, irrigation, coppicing and hedge laying.

The most critical aspect of wildlife conservation is habitat management. Habitat loss presents the greatest threat to wildlife.

Five essential elements must be present to provide a viable habitat: food, water, cover, space, and arrangement.

Adult animals that survive hunting can be affected by experiencing mental stress and disruption to the social structure if they are a species that live in a group. ... Hunting with firearms and dogs close to native animals and livestock can also disturb them and cause fear.

Manipulative management involves regulating numbers of animals directly by harvesting or by influencing numbers by altering food supply, habitat, density of predators etc. Custodial management is preventive or protective and minimizes external influences on the population and its habitat.

Wild animals are used in medicine for essential research; wild plants provide a source of drugs, and wild places can help to relieve the tension and stress associated with modern living. Wildlife is also a sensitive indicator of environmental change.

Habitat is the area in which a species lives. Simply stated, habitat is made up of four basic requirements for survival: sufficient space, food, water and shelter. ... Your backyard habitat can provide food, water and shelter even though you may have limited space.

Characteristics of habitats are the abiotic and biotic factors that influence a plant. Among the abiotic factors are chemical and physical values like light, climate, soil composition, soil consistency, exposition to the sun, etc.

Wildlife management can be defined as the manipulation of wildlife populations and habitat to achieve a goal (Sargent and Carter, 1999). Aldo Leopold defined game management as the art of making land produce sustained annual crops of wild game for recreational use.

These are lands which are set aside for the purpose of increasing wildlife numbers by protecting wildlife and key habitat. One of the major goals of a wildlife management areas is to protect at least a minimal number of animals so the population can increase. ... Damage to the habitat then occurs.

klasskru [66]
Give two examples each for conduction, convection, and radiation.

Conduction - heating a tin can with the use of a bunsen burner, a cold iron skillet placed on a stovetop which is hot
Convection - boiling of water, hot air balloon
Radiation - UV from the sun, x-rays from an x-ray equipment

Find out whether combustion reactions are exothermic or endothermic, and explain why.
Combustion reactions are exothermic reactions since they always produce or release heat. The reactants would always have more energy than the products which causes the excess heat to be released.

<span>Find a substance that has a specific heat that is higher than liquid water and explain what it means.
The substance which has a higher heat capacity than water would be the hydrogen gas. It has a heat capacity of 13.83 kJ/kg K. Having a higher heat capacity would mean that it requires more heat energy in order to increase the temperature as compared to water.
