Is the major factor affecting the distribution of plants and determining their structural adaptation?
Soil structure, pH, and its nutrient content affect the distribution of plants, which in turn influences the distribution of the animals that feed on them. Oxygen availability is an important abiotic factor affecting species in both aquatic and terrestrial environments.
What are two main types of dry climates and how are they distinguished from each other?
There are two dry climate types: arid and semiarid. Most arid climates receive 10 to 30 centimeters (four to 12 inches) of rain each year, and semiarid climates receive enough to support extensive grasslands. Temperatures in both arid and semiarid climates show large daily and seasonal variations.
What determines which type of plants and animals can survive in tropical dry climate?
What determines which type of plants and animals can survive in tropical dry climates? The length and severity of the dry season determines the type of plants and animals that can survive. … The humid subtropical climates are characterized by short, mild winters and nearly year-round rain. Humidity levels are high.
What factors determine the distribution of plants and animals?

Why are plants and animals affected by abiotic factors?
The abundance of organisms in an ecosystem and their distribution is affected by abiotic factors. These are factors that are non-living. light is required for photosynthesis , and plant species have evolved for optimum growth in the light available in their climate or habitat.
What are the factors that determine climate?
Introduction: Climate is determined by the temperature and precipitation characteristics of a region over time. The temperature characteristics of a region are influenced by natural factors such as latitude, elevation and the presence of ocean currents.
What makes the climate dry?
Low and unpredictable precipitation is the primary characteristic of a dry climate. The lowest rainfall occurs in arid, or desert, areas where precipitation averages less than 35 cm (14 inches) per year, and some deserts have years with no rainfall at all.
What two factors are generally used to classify climates?
The two most important factors in the climate of an area are temperature and precipitation.
What determines the types of plants and animals that live in a biome?
Climate is a major factor in determining types of life that reside in a particular biome, and there are several factors that influence climate, such as latitude, geographic features, and atmospheric processes disseminating heat and moisture. The number of biomes that exist is debated by scientists.
What is the main factor that determines plants grow?
There are four primary factors that affect plant growth: light, water, temperature and nutrients. These four elements affect the plant’s growth hormones, making the plant grow more quickly or more slowly. Changing any of the four can cause the plant stress which stunts or changes growth, or improves growth.
What two factors determine the type of vegetation?
Climate, soil, the ability of soil to hold water, and the slope, or angle, of the land all determine what types of plants will grow in a particular region.
How do plants adapt to the tropical dry forest?
Therefore, many tropical dry forest plants have evolved methods of conserving water to cope during these dry periods. These adaptations include shedding leaves during the dry season, storing water in their body tissue and developing protective spines, thorns and other structures.
What abiotic factors affect plant and animal species diversity in wet tropical forests?
Climate, soil type, precipitation, temperature and sunlight are all abiotic factors that determine the composition of a rainforest, including the major differences between rainforests in tropical and temperate regions of the globe.
What plants live in tropical dry forest?
Drought-resistant epiphytes (orchids, bromeliads and cacti) may be abundant. The trees have thicker, more ridged, bark; deeper roots without buttresses; much more variable leaves, including many compound-leaved legumes; and more species with thorns.
