Factors affecting different types of habitat

Habitat can be defined as the natural environment of an organismthe type of place in which it is natural for it to live and grow. Generally speaking, animal communities are reliant on specific types of plant communities. The small white butterfly Pieris rapae for example is found on all the continents of the world apart from Antarctica. Its larvae feed on a wide range of Brassicas and various other plant species, and it thrives in any open location with diverse plant associations.

Seawater has an average salinity of 35 parts per thousand of water. Actual salinity varies among different marine ecosystems. Marine ecosystems can be divided into many zones depending upon water depth and shoreline features. The oceanic zone is the vast open part of the ocean where animals such as whales, sharks, and tuna live.

The benthic zone consists of substrates below water where many invertebrates live.

Introduction

The intertidal zone is the area between high and low tides; in this figure it is termed the littoral zone. Other near-shore neritic zones can include estuariessalt marshescoral reefslagoons and mangrove swamps.

In the deep water, hydrothermal vents may occur where chemosynthetic sulfur bacteria form the base of the food web. Classes of organisms found in marine ecosystems include brown algaedinoflagellatescoralscephalopodsechinodermsand sharks.

Fishes caught in marine ecosystems are the biggest source of commercial foods obtained from wild populations. Freshwater ecosystem Freshwater ecosystem. Freshwater ecosystems cover 0.

Lake ecosystem The three primary zones of a lake. Lake ecosystems can be divided into zones. One common system divides lakes into three zones see figure. The first, the littoral zoneis the shallow zone near the shore. This is where rooted wetland plants occur. The offshore is divided into two further zones, an open water zone and a deep water zone.

In the open water zone or photic zone sunlight supports photosynthetic algae, and the species that feed upon them. In the deep water zone, sunlight is not available and the food web is based on detritus entering from the littoral and photic zones.

Some systems use other names. The off shore areas may be called the pelagic zonethe photic zone may be called the limnetic zone and the aphotic zone may be called the profundal zone. Inland from the littoral zone one can also frequently identify a riparian zone which has plants still affected by the presence of the lake—this can include effects from windfalls, spring flooding, and winter ice damage.

The production of the lake as a whole is the result of production from plants growing in the littoral zone, combined with production from plankton growing in the open water. Wetlands can be part of the lentic system, as they form naturally along most lake shores, the width of the wetland and littoral zone being dependent upon the slope of the shoreline and the amount of natural change in water levels, within and among years.Animal Habitat and Environmental Factors Dr.

John Fischer Dr. Marc Artois. Landscape (habitat) & natural barriers can limit the geographic spread as with sylvatic rabies progression in Europe.

Habitat - Wikipedia

Local Influence of Habitat •Suitability of habitat for sylvatic, feral, or stray. A fish’s habitat includes all the required physical factors (temperature, water depth, current, waves, bottom types, cover, etc.) and chemical factors (oxygen levels, dissolved minerals, and.

Video: Pollution and Habitat Destruction: The Human Factors Contributing To Endangerment & Extinction In this lesson you will learn about two ways humans contribute to species extinction. Variability and change are natural processes in aquatic ecosystems, and ecosystem communities and individual organisms have in many cases adapted to different environmental conditions.

Human effects on aquatic ecosystems can result from pollution, changes to the landscape or hydrological systems, and larger-scale impacts such as .

Stress Related Factors in Different Types of Schooling Stress is the body's way of rising to a challenge and preparing to meet a tough situation with focus, strength, stamina, and heightened alertness. Every individual will stress at some point. Other factors that influence animal population size include water, habitat, competition, predation, and lots more.

This lesson will cover them. Light and Nutrition.

Abiotic factors vary in different geographical locations. What factors affect the light intensity value in a given habitat? vegetation is a great factor about this. While there are small factors that may influence a particular environment -- or habitat -- from time to time, four major factors affect the carrying capacity of the environment. Food Availability Food availability in any habitat is paramount to survival of a species. Biotic factors in an ecosystem are simply living factors that have an effect on the said ecosystem.. For example, if you had an abundance of lynxes (they're a type of fox) in a given area, then there is a good chance that you'll have a limited number of hares in the area as well (because lynxes eat hares).
