BIO DEPTH STUDY

Structural Adaptations

Anatomical or morphological features that improve an organism’s ability to cope with biotic and abiotic factors, increasing chances of survival and reproduction.

Xerophytes

Plants that have adaptations to conserve moisture and prevent leaf temperature from rising too much, found in hot, dry environments.

Physiological Adaptations

Features that affect the functioning of an organism at different levels of organization, such as water conservation in plants or thermoregulation in animals.

Crassulacean Acid Metabolism (CAM)

A process in some plants where stomata only open at night to collect carbon dioxide, minimizing water loss during the day.

Frost Tolerance

The ability of some organisms to survive cold temperatures by using high concentrations of solutes to lower the freezing point and prevent cell damage.

Halophytes

Plants that can survive in high salinity environments by regulating salt concentrations.

Camouflage

A behavioral adaptation where organisms change colors to match their surroundings, aiding in predator avoidance or prey capture.

Thermoregulation

The process of maintaining an optimal body temperature through physiological changes such as sweating, shivering, and altering blood flow.

Ecological Niche

The role and position a species has within its environment, including how it uses its resources and interacts with other organisms.

Carrying Capacity

The maximum population size that an environment can sustain based on available resources.

Competitive Exclusion Principle

The concept stating that two species cannot coexist if they occupy the same niche; one will outcompete the other.

Resource Partitioning

Differing species using different parts of a resource to minimize competition and coexist.

Symbiosis

A close interaction between two different species where at least one species benefits, such as mutualism, commensalism, and parasitism.

Biogeography

The study of species distribution to understand their evolutionary past and the biotic and abiotic factors impacting their current distribution.

Population Dynamics

The study of how populations change in size and structure over time, influenced by factors like predation and competition.

Selection Pressure

Any factor that influences the survival and reproduction of organisms, leading to evolutionary changes.

Evaporative Cooling

A cooling process where sweat evaporates from the skin surface, helping to lower body temperature.

Torpor

A state in which an organism's metabolic activities are significantly reduced to conserve energy during adverse conditions.

Bioluminescence

The production of light by living organisms, often used for attracting mates, luring prey, or deterring predators.

Invasive Species

Non-native species that spread rapidly in a new environment, often causing harm to native populations and ecosystems.

Ecosystem Dynamics

The complex interactions within and between different ecosystems, driven by biotic and abiotic factors.

Abiotic Factors

Non-living components of an environment, such as temperature, water, sunlight, and soil.

Biotic Factors

Living components of an environment, such as plants, animals, fungi, and microorganisms.

Keystone Species

Species that have a disproportionately large impact on their environment relative to their abundance.

Antifreeze Proteins

Proteins that prevent the growth of ice crystals inside cells, thereby protecting organisms from freezing.

Evaporative Cooling for Heat Exchange

A mechanism in which warm arterial blood is cooled by cooler venous blood to prevent overheating.

Population Explosion

A rapid increase in population size when individuals reproduce at a rate that far exceeds the carrying capacity.

Environmental Resistance

Factors that limit the growth of populations by reducing health, reproduction rates, and survival.
