Abstract
Every individuals or organisms dwell in a place where well suited for their growth and development, survival and reproduction. When changes happened to their environment expected changes will also be observed and adaptation mechanisms are produced. This study focuses on the responses of modular and solitary organisms under their normal environmental condition and on their disturbed or changed environment. The study further focuses on how long the unitary organisms respond to certain disturbances and how modular organisms respond to lessen the effect of environmental changes happening on their surroundings. Ant’s behavior in three different activities under normal conditions was observed and their response also under disturbed conditions was also observed by inducing commotion to their environment. Moreover, ants were also tested on which food they are most likely be attracted, results showed that they prefer sweeter food sources rather than the salty ones. On the other hand, two sets of modular organisms were subjected to environmental changes, a set for the sun-loving plants (Cyperus and Althernanthera) and shade-tolerant plants (Zebrina and Talinum) were interchangeably exposed to each other’s environment. Results generally showed that when plants are put into an environment where they are not used to, they tend to grow poorly and vice versa. But some developed mechanisms to lessen the impact of the stress applied to them. In conclusion, unitary animals adjust faster than modular organism because they communicate and work with each other but modular organisms have unique ways of

    White Bird-of-Paradise is most often planted for its large, banana-like leaves and upright, clumping stalks which give an exotic feel to the landscape (Fig. 1). Plants can reach 20 to 30 feet in height with a spread of 10 feet though they are often seen much smaller. The five to eight-foot-long, cold-tender leaves are arranged in a fanlike display from the erect trunks and appear much like Traveler’s-Tree. The lower trunk becomes clear of leaves and exposed as the older leaves drop off. Leaves rip along the veins as they are blown by strong winds.…

    Between plant species the rate of decomposition varies according to leaf structure, chemical or physical defence and whether the species is allochthonous or autochthonous. Native species adapt to the predators that feed upon them and the same applies for the predators, adapting to the plants defences. Allochthonous species have not evolved with the native predators in its introduced environment. In some cases this can result in the plant being more susceptible to predation.…

    By Helen Ying © 2013 Biology Notes – HSC Course 2013 MODULE 9.3 – BLUEPRINT OF LIFE 1. Outline the impact on the evolution of plants and animals of: a. Changes in physical conditions in the environment o Rising and falling sea levels – land and ice bridges across continents have affected distribution and therefore evolution when these bridges disappeared and populations were isolated from the main population. o Fossil evidence indicates mass extinctions resulting from changes in the physical environment e.g. dinosaur extinction from meteor. o Movement of continents. As Australia moved north, it became drier and plants and animals needed to adapt to these new conditions. b. Changes in chemical conditions in the environment o Original anoxic environment. As primitive organisms metabolised, carbon dioxide was released. Over millions of years, carbon dioxide accumulated and at some stage, organisms capable of using carbon dioxide in photosynthesis evolved and became dominant. Oxygen was then released as a product of photosynthesis, and oxygen-using organisms became dominant. c. Competition for resources o During the Cretaceous period, mammals were limited to the niches in which they originally evolved because the world was dominated by dinosaurs. When the dinosaurs died, the mammals were able to populate larger areas of the world as they had few competitors. As they populated these different areas, they evolved into new species to adapt to these new conditions. o Long-term competition usually results in one of the species dying out or evolution of one of the competing species so that they can occupy a different environment.  Organisms alive today have all arisen from simpler organisms that existed millions of years ago.  Evolution is the change in living organisms over many generations.  Changes in the environment of living organisms can lead to the…

    There are many factors that account for the changes to the vegetation over time within ecosystems in the British Isles, such as human activity, climate, soil, light availability and intensity and natural disasters. The characteristics of the vegetation that are influenced by these factors are height, distribution, variety of species, adaptations and density of the vegetation. Some of these factors have relatively little influence on the succession development, whereas others have a dramatic influence over a long period of time, such as human activity. These factors, over time, result in the progression of a succession until the climatic climax vegetation is reached. However, sometimes these factors can mean that a plagioclimax is reached, as they prevent the succession from progressing any further and the climatic climax vegetation is never achieved, which in the UK are Oak, Hawthorne and Birch trees. This succession results in the development of an ecosystem. An ecosystem is a dynamic, stable environment which is composed of interacting and functioning biotic and abiotic components and can be of any size. There can be composed of variety of successions, such as lithoseres in grassland and woodland areas for example the Isle of Aaron, psamoseres along the coastline or small scale urban successions in urbanised areas.…

    An experiment by Matos tested the phenotypic plasticity to light availability in shade and sun leaves of coffee trees (Matos et al., 2009). Their research indicated that "compared [to] sun leaves, shade leaves had a lower stomatal density, a thinner palisade mesophyll, a higher specific leaf area, and improved light capture…" (Matos et al., 2009). The sun leaves were described as "generally thicker with an enhanced quantity of palisade mesophyll" (Matos et al., 2009).…

    A savanna, or savannah, is a grassland ecosystem characterized by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses.[1][2][3] The oak savanna is a common type of savanna in the Northern Hemisphere. Some classification systems[which?] also recognize a grassland savanna from which trees are absent.[4] This article deals only with savanna under the common definition of a grassy woodland with a significant woody plant component.…
