Plant/Animal Relationships - Brooklyn Botanic Garden
Plants and animals interact with each other in the environment. They also interact with the environment itself. The plants and animals depend. The natural environment plays an important role not only in practical are of vital importance, the relationships between plants, animals and man differ. The environment in which an animal lives in is referred to as its habitat. Plants, animals, and even humans choose habitats for many different reasons.
Undisturbed plots at low elevations around m a. At m, coffee plantations and agroforestry systems harbored mostly dicotyledonous weeds.
Grasslands were dominated by several taxa of Poaceae.
Woody life forms accounted for the largest part of plant biomass from middle to upper elevations, with a transition from rainforest to cloud forest characterized by small trees and high lichen abundance at around m.
Alpine vegetation occurred up to m and was mainly composed of shrubs, perennial herbs, and grasses. Mean temperature was derived from several years of continuous measurements with automatic data loggers covering the time period of our data collection [ 42 ].
Relationship Between Plants and Animals by Oliver Freeman on Prezi
Annual precipitation data was derived from the Kilimanjaro rainfall model [ 43 ]. Disturbance was calculated as a composite metric including the effects of land use at local and landscape scales [ 44 ], S1 File. Abundance was defined as percent cover determined from vegetation surveys. Cover was estimated for each stratum depending on the vegetation structure of the plot.
How do plants affect the environment?
Plant functional traits were chosen to indicate vegetative growth, persistence, and reproductive characteristics. Fifteen individuals per species were sampled from different plots within the elevational distribution range for specific leaf area SLAleaf dry matter content LDMCstem specific density SSDleaf nitrogen content leaf Nmassleaf phosphorus content leaf Pmassfruiting frequency, fruit number, and fruit size.
Additionally, the total plant biomass per plot was calculated with allometric equations using complete tree and undergrowth inventories details in [ 45 ]. Sampling and processing of plant material followed Kleyer et al. Percentage cover values from vegetation surveys were used to calculate community-weighted mean trait values for each plot CWM, [ 47 ].
The traits used are related to the worldwide leaf economics spectrum [ 3248 ], reflecting a gradient from plants with fast resource use and nutrient turnover to those with slow and persistent growth. The former are characterized by soft tissues with high nitrogen content and are generally preferred by herbivores, due to their easier digestion and higher nutritional value [ 32 ].
All data were collected on the same plots within a common time frame to avoid confounding effects of spatial and temporal variability. To quantify nectar and fruit availability on the plots, pollination and dispersal syndromes were extracted from the Flora of Tropical East Africa [ 49 ].
Nectar availability is difficult to quantify, as nectar amounts per flower, flowering times, and the proportion of tissue invested in flowers are highly variable between species.
This resource was approximated by the abundance-weighted proportion of insect-pollinated plant species. They write about it in their Science Journals. Students combine their individual studies to determine the relationships between the different plants and animals they have studied. Students make presentations to the class about the plants and animals they studied. In their Science Jorunals, all students write about the plants and animals in the environment.
- Plant/Animal Relationships
Students develop food chains based on the relationships they have discovered between the plants and animals. Students make posters about their food chains using pictures as illustrations. Once the individual food chains are completed, they are studied by the class to see if there are any common organisms and pathways.
The food chains are then combined into a food web.

They draw the food web in their Science Journals. Students investigate other ecosystems and habitats that they have not studied or that are not found in New Jersey. Consumers - decomposers and transformers After a while, some of the producers and the consumers die.
When they do, the decomposers and the transformers recycle them to be returned into the soil. The decomposers and the transformers mainly free the elements contained in the dead plants and animals so that they can be returned to the soil. This category of consumers lives on the floor of the forest. Examples include fungi and bacteria, collectively called micro-organisms. They go into motion after the producers and the consumers die. The bodies of the dead animals and plants are literally eaten by the decomposers and transformers.
This happens in two stages; first the decomposers convert the complex organic materials into simple organic compounds. Then second, the transformers convert the simple organic compounds into simple inorganic forms.

After these, the freed elements are returned to the abiotic form to be utilized again by the producers and the consumers. Thus the cycle continues. Conclusion From the above discussion one can see the interrelationship that exists among the various players in the forests.
