Acche Marks Behavioral adaptions in animal Certain animals exhibit behavioral responses to cope with environmental variations. For instance, desert lizards maintain a relatively constant body temperature through adaptive behaviors. They bask in the sun to absorb heat when their temperature drops, and seek shade as ambient temperatures rise. Similarly, snakes engage in basking during winter months. These … Read more
Adaption of plants to water scarcity 1. Desert plants exhibit a thick cuticle on their leaf surfaces, providing a protective barrier to minimize water loss. 2. The stomata of these plants are sunken into deep pits, a adaptation that helps reduce water loss through transpiration. 3. Specialized in Crassulacean Acid Metabolism (CAM), desert plants utilize … Read more
Adaption of desert animals 1. Xerocoles, adept desert dwellers, exhibit adaptations for water conservation and heat tolerance, often obtaining moisture from succulent plants without frequent water intake. 2. Examples like Gazella and Oryx showcase low basal metabolic rates, relying on specialized mechanisms for survival, such as concentrated urine and dry dung production. 3. Numerous hot … Read more
Parasitism In a parasitic relationship, one organism gains benefits at the expense of the other, which experiences harm. The parasite relies on a host for survival, but if the host is excessively exploited, the parasite also perishes. Mutualism Mutualism describes a symbiotic relationship in which organisms from different species mutually benefit from each other. Both … Read more
Ectotherms Ectotherms lack the capacity to internally produce heat in their bodies. Ectotherms rely on external sources, such as sunlight, to regulate their body temperature. Endotherms Endothermic organisms have the capacity to internally produce their own body heat. Endothermic organisms generate heat internally and do not rely on external sources for warmth.
Hibernation Hibernation is a state of winter dormancy observed in certain warm-blooded and cold-blooded animals. Throughout the entire winter. Aestivation Aestivation refers to the summer dormancy observed in cold-blooded animals. Animals seek out a damp, shaded, and cool spot for resting.
1. Orchids, as epiphytes, rely on mango trees for support without causing any harm to them. 2. The mango tree, despite providing support, does not receive any benefits from this association with the orchid. 3. The interaction between the orchid and mango tree is characterized as commensalism, where one species benefits (orchid) while the other … Read more
Morphological defense mechanisms: 1. Opuntia and cactus leaves undergo morphological changes, transforming into sharp spines or thorns, serving as a defense mechanism to deter herbivores from feeding on them. 2. Certain plants exhibit spiny leaf margins, creating sharp edges that pose challenges for herbivores attempting to consume them. 3. Acacia plants employ a defense strategy … Read more
1. Marine fish possess distinct osmoregulation mechanisms tailored for high-salinity environments, where ambient salinity exceeds their body’s ion concentration. 2. In marine water, the salinity levels are higher than the fish’s internal ion concentration, necessitating specialized adaptations for osmoregulation. 3. The reverse scenario occurs in fresh water, where the ambient salinity is lower than the … Read more
1. Dormant seeds exhibit no metabolic activities and can only resume growth when provided with adequate moisture and sunlight, typically through planting or exposure to a moist environment. 2. Hibernation is a state of reduced metabolic activity in animals, and their awakening is spontaneous, influenced by ambient temperature, occurring naturally after the winter sleep period.
