The acacia tree requires ant mutualists for its survival, and as soon as one ant colony moves to an acacia tree they will remain them. From the perspective of the acacia tree, what is the exchange, intimacy, and dependency of this interaction? Defensive, intimate, facultative Defensive, intimate, obligate Resource acquisition, intimate, facultative Resource acquisition, intermittent, obligate

How can altruism be adaptive if it can result in fewer offspring for an individual?

Please create a very detailed experiment regarding the following ultimate hypotheiss about meerkats behavior but withan assumption that there are unlimited resources.

What is said to occur when one organism obtains nutrition from another organism by living on or in the other organism? Interspecific competition Predation Parasitism Mutualism Commensalism

true/false 1. Large Aspen Tortrix (Choristoneura conflictana) makes a large silken tent and uses it as a communal place. 2. Trichoptera has hairy wings.  3. Black Fire Beetle (Melanophila acuminata) has infrared receptor so that they can detect burned forests. 4. White-spotted Sawyer (Monochamus scutellatus) belongs to the family Buprestidae and makes D-shaped emergence holes.

Which of the following statements most accurately describes the example of species interactions for ants, plants and aphids    Question 2 options:   The burdock plant is negatively affected by a heavy aphid investation, the ants are negatively affected by the aphids and aphids are positively affected by the ants.   The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are not affected by the ants   The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.   The burdock plant is not affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.

Which of these following scenarios is caused by the Allee effect? Corals rely on external fertilization when gametes (sperm and eggs) are released into the sea in large quantities and have to meet at random chance. When coral densities drop due to coral bleaching and die back, external fertilization becomes inefficient, few zygotes form, and coral populations further decline or go extinct. After a big disturbance in forests, such as fire, many seeds germinate and seedlings compete for space, light and resources. K-selected species produce fewer, but larger seeds that are initially outnumbered by the numerous sEeds and resulting seedlings of r-selected species. The initial advantage of r-selected species of Occupying more locations and therefore by random chance also better locations, is later overcome by the K-selected species higher competitive ability. Therefore, for the first years to decades, r-selected species dominate areas that experienced severe disturbances, while in mature…

Moths resting on the trunks of trees often resemble the tree bark such that potential predators do not perceive them as prey. This is an example of:   an induced defense. aposematic coloration. crypsis. silencing.

The Two-Sided Attack on the Spiny Cactus The spiny cactus is a type of plant that lives in a desert environment. A population of spiny cacti shows variation in the number of spines on their outer surfaces. The graph below shows the distribution of the number of spines before the introduction of collared peccaries and parasitic wasps. Spiny Cactus Organism Collared peccary (musk hog) Number of Cacti Parasitic wasp 300 200 100 T Collared peccaries and parasitic wasps are two organisms that were introduced to the ecosystem in which the spiny cactus population lives. The chart describes the relationship between the spiny cacti and these two organisms. 70 1 1 80 90 100 110 120 130 Number of Spines Organisms Introduced into the Ecosystem Relationship with Spiny Cactus Plants They eat spiny cactus plants that have a small number of spines. They lay eggs at the base of cactus spines. When the eggs hatch, the emerging grubs dig into the interior of the cactus and eat the inner pulp of the…

Is the following case study an r-strategists or a K-strategists? Andean condors reach sexual maturity at five to six years. Reproduction is slow; females lay only one or two eggs every other year. Offspring are cared for by both parents for at least one year. Andean condors are long-lived and can survive for seventy to seventy-five years.
