Jennifer Aguilar April 11, 2016 Agroecology INTRODUCTION: For this lab the concept of intraspecific and interspecific competition was used in order to carry out this experiment using seeds kale and radish seeds. Intraspecific competition is when the many of the same type of species, for example kale, compete for the same resources such as sunlight, water, and nutrients. Yes, they are the same, but in order to survive, and thrive, they must compete with those around them. Intrespecific is different

Competition in ecosystems has become central to the study of ecology, and has been implicated as a major factor behind the patterns of species abundance and distribution. Though often studied together, abundance and distribution are two distinct designations, abundance being the density of a species in a given area, and the spatial arrangement of that species in an area is referred to as the distribution (Brown, 1984). In ecological terms competition refers to a fight between two organisms, of the

Discussion Commonly speaking, the theoretical and practical outcome of corresponding experiments done before should be similar with the results of this time. “The exponential model approximates population growth in its early stage. Table 3.4.1 shows the numbers generated by an organism that doubles at each cycle. Table 3.4.1: Number of Generations: 0 1 2 … 10 … 25 … 40 … 72 Number of Organisms: 1 2 4 … 1024 3.4 x 10^7 1.1 x 10^12

Introduction Competition happens between two or more things. In talking about plants they compete with each to survive. When competing against each other to survive they are using soil, water, nitrogen, and space. In using theses resources and having theses available gives the plant a greater chance in living. Even though plants compete environmental wise it is still scene that there is a lot of unknown to why plants compete. Some researchers believe it could be because of the root size of an

Biology essay – Relationships and interactions There are many different types of relationships and interactions between organisms. Every organism is in some way connected or associated with another. Some organisms need to depend on other organisms to survive which shows how important some of these relationships or interactions can be in biology. Interaction is a vital part of how many organisms develop over time. Predation is a main example of a relationship between organisms. Predation involves

which means “competition between same species” (1976). The second type of competition is interspecific, which is defined as “competition between different species” (1976). These two types of competition have helped us look at the different types of interactions

Plant Interaction Paper Organisms interact in ways that affect themselves in a positive or negative manner, either benefiting or harming one or both organisms. For example, in mutualism, organisms interact in a positive way that benefits them both. Competition is a negative interaction in which the organisms harm each other, and this is over a limiting resource, which is oftentimes food, water, or other necessities to the organism’s well being. There are two types of competition: interspecific

A plant's growth ability is dependent on its ability to acquire the resources it needs to survive. Competition such as interspecific and intraspecific, limiting resources, and population density affect the fitness level of a plant. This experiment was conducted in order to test the capability of collards and radishes to grow in manipulated densities under interspecific and intraspecific competition. I hypothesized that both collard and radish plants will grow more efficiently in single species pots

of competition among plants at different population densities on the growth of plants 2. To assess the relative competitiveness of two species of plants when they are planted together Background: Competition is an interaction between organisms in which both are harmed by the interaction. Competition can occur among members of the same species and is called intraspecific competition or it can occur between members of different species, in which case is called interspecific competition. Competition

Enduring Understanding 4.A: Interactions Within biological systems lead to complex properties. Overview Almost every aspect of biology involves interaction between different components and systems. It starts all the way at the cellular level with the interactions of cell organelles that allow a cell to function and it goes all the way up to the way different ecosystems come together to form complex communities and interactions. It is these interactions that make biological systems complex and how cells
